SYST M OV RVI W
The horizontal electrophoresis systems PerfectBlue™ Maxi S, Maxi S Plus, Maxi M ('Revolution'), Maxi L
and Maxi xW ('Revolution') are designed for the separation of medium to high sample numbers at
long distances and provide flat, even banding patterns and consistent results. The gel trays are sealed
inside the chamber by using nd Gates included in delivery. These gasketed nd Gates are specifically
engineered to fit accurately into the gel tray grooves eliminating the need to tape or seal the tray before
pouring gels. Utilizing the built-in leveling feature in all of the horizontal Maxi Gel Systems allows the
user to cast level gels quickly. Four gel sizes are available to provide maximum versatility. Depending
on the specific model, the UV-transmissible gel trays are equipped with 4 to 12 comb slots so that you
can run multiple sample sets to equal distances simultaneously.
VWR offers a wide variety of standard and microtiter combs in two different thicknesses (1 mm or 1.5
mm). Microtiter combs allow for speedy sample loading using a multi-channel pipette. Additional pre-
parative combs for large sample volumes and wall combs and casting dams to cast gels in smaller sizes
are available for increased versatility. For dividing up the gel tray, wall combs are put in the gel tray's
slots instead of a common comb but should get sealed using agarose of higher percentage before cast-
ing the gel. Casting dams can be inserted at any position into the gel tray. Due to the optimal fitting and
the heat conductance of the material neither adhesive tape nor concentrated agarose is required for
sealing by using the casting dams.
For detailed information on available accessories visit www.de.vwr.com or see 'T CHNICAL SUPPORT
AND ORD RING INFORMATION'.
The Maxi M 'Revolution' and Maxi xW
'Revolution' models are equipped with an inter-
nal buffer recirculation system. A trapping sys-
tem captures hydrogen bubbles which are pro-
duced at the cathode due to electrolysis, and
directs them through an ascending tube to the
opposing side of the buffer chamber where the
anode is located. During this hydrogen bubble
migration, the buffer circulates, preventing the
creation of detrimental pH or ion gradients.

G N RAL INSTRUCTIONS
Setting up the system and pouring the agarose gel
1. Remove the lid from the gel box by holding the front of the buffer chamber with one hand and pull-
ing the lid off by holding the center of the back of the lid.
2. Slide the gasketed nd Gates into the outermost grooves on either side of the gel tray. The nd
Gates should be inserted tightly into the grooves with the gasket side facing out. Insert the sealed gel
tray into the buffer chamber and level the system by using the integrated three-point adjustable lev-
eling platform with bubble level.
Optional: The gel tray can be subdivided by a wall comb available as an accessory to pour shorter
gels. The wall comb should be sealed with 2 % agarose before pouring the real gel.
Alternatively, a casting dam available as accessory can be used for this purpose. This aluminum bar
can be inserted at any position into the gel tray. Due to the optimal fitting and the heat conductance
of the material neither adhesive tape nor concentrated agarose is required for sealing by using the
casting dams.
3. Use electrophoresis-grade agarose and compatible electrophoresis buffer to prepare the gel. The
percentage of agarose and the buffer to be used is determined by the size of the samples to be sep-
arated and further recovery of the samples (see 'R QUIR D R AG NTS & R CIP S'). The agarose
and buffer are mixed and heated over a heat plate by stirring or in a microwave oven until the
agarose is completely dissolved.
4. The prepared gel then must be cooled to below 60 °C before casting to avoid warping the UVT gel
tray due to excessive heat. If numerous gels are to be run in one day, a large volume of gel may be
prepared and be placed in a covered bottle stored 60 °C in a water bath.
5. Pour or pipette the measured amount (see 'Agarose: Gel volumes and percentage') of warm
agarose (< 60 °C) onto the UVT gel tray that has been placed into the correct position in the gel
box. Immediately after pouring, insert the desired comb or combs into the comb slots to form the
sample wells. Standard agarose should solidify completely in about 30 minutes. If low melting
agarose or a specialty agarose is used, please consult the instructions that came with the product.

Loading of samples and electrophoresis
1. Once the gel is completely solidified, remove the nd Gates by carefully lifting out of the tray.
2. Pour enough compatible running buffer into the unit to fill chamber and completely cover and sub-
merge the gel. A 'Fill Line' is located on each unit to clearly mark the correct buffer level. See
'Technical properties' for approximate buffer volumes needed for your unit. Too little buffer may
cause the gel to dry out during the run, while excess buffer may slow DNA migration in the gel, in-
crease heat build-up and cause distorted bands.
3. Carefully remove the comb (or combs) by tapping lightly to loosen, and slowly lift straight up out of
the gel tray to avoid damage to the wells.
4. Load prepared samples into the wells. Samples should be mixed with a sample loading buffer (giv-
ing weight to the samples so that they drop evenly into the wells), and contain tracking dye to moni-
tor the gel run. For details on approximate well volumes see 'T CHNICAL SUPPORT & ORD RING
INFORMATION'. If microtiter combs have been used wells can be loaded by a multi channel pi-
pette. Wells that have been cast with microtiter combs of 26 teeth or less can be loaded 'directly',
i.e. the pipette tips fit sequentially into the gel wells. For gels prepared with microtiter combs with
more than 26 teeth the wells can be loaded 'shifted', i.e. the pipette tips fit only into every second
well.
NOT : It is wise to always run a sample lane of a known 'standard ladder' to determine concentra-
tion and size of separated fragments after the gel run, and to aid in photo documentation and anal-
ysis.
5. Carefully slide the lid with attached power cords onto the unit. This will connect the power cords to
the banana plugs to complete the circuit. Plug the other end of the power cords (4 mm, male) into
an appropriate power supply.
Take care to the proper orientation of the electrical field. Remember that nucleic acids are negatively
charged in an alkaline to neutral surrounding and therefore will migrate to the positively charged
anode. In general the color coding for positively charged electrodes is 'red'.
6. Turn on the power supply and run the gel at the appropriate voltage/current (see 'Technical proper-
ties'). You can observe the progress of electrophoresis by the visual migration of the loading dye.
Note that in 0.5 x TB gels, bromophenol blue co-migrates at 300 bp and xylene cyanol at 4 kbp
with the DNA fragments.

Visualization
When the tracking dye has migrated as far through the gel as desired, or to the end of the gel, turn off
the power supply and slide off the lid to disconnect from the power source. Carefully remove the tray
containing the gel (wear gloves). The UV-transmissible gel tray makes for simple visualization and pho-
tography with a UV light source without the need to remove the gel from the tray. The gel tray may be
placed back into the casting chamber for convenient transport to the darkroom and to avoid damage to
the gel.
Cleaning
The buffer chamber, tray, combs and nd Gates should be rinsed under warm running water after each
use. Use a mild detergent to get rid of any debris. A following short rinse off with distilled water pre-
vents the formation of salt marks. It is recommended to allow the chamber to air dry rather than drying
with a towel to avoid damage to the electrode wires.
Do not use ethanol or other organic solvents to clean acrylic products, because organic solvents cause
acrylic to 'craze' or crack!

lectrophoresis buffers
lectrophoresis buffers supply the ions necessary for electrophoresis and establishing a certain pH value
in which the target molecule adapts to its the required electric charge. Nucleic acids for example will be
negatively charged in an alkaline to neutral surrounding. Additionally, electrophoresis buffers often
contain reagents which protect the target molecule from degradation (e.g. DTA, which complexes biva-
lent cations and therefore inhibits DNases). If electrophoresis under denaturing conditions is desired
(like for the electrophoresis of RNA), electrophoresis buffers will additionally contain reagents that elimi-
nate the formation of secondary structures.
You will find recipes below for TA and TB , two of the most commonly used buffers for the electropho-
resis of DNA. If the intention is to eventually isolate DNA from the gel, TA buffer should be chosen. In
comparison to TB , migration will be faster and a better resolution of supercoiled DNA will be achieved
when using TA . However, because of TA 's limited buffering capacity, TB should be selected for per-
forming extended electrophoresis separations and if the electrophoresis chamber does not possess a
system for buffer recirculation. VWR's PerfectBlue 'Revolution' Systems are equipped with an internal
buffer recirculation system that prevents the formation of pH and ion gradients during extended runs.
Since agarose tends to create finer pore sizes and a more solid matrix in TB , diffusion of DNA will be
reduced and a more discrete band pattern will be achieved.

1 x working solution: 40 mM Tris-acetate, 1 mM DTA

* 0.5 x TB is sufficient for agarose gel electrophoresis. For vertical electrophoresis in polyacrylamide gels,
1 x TB is often applied due to the comparatively smaller buffer reservoirs of vertical electrophoresis chambers.
** 5 x TB stock solutions tend to precipitate during long storage periods and should get remade. Because of this
property, higher concentrations of TB stock solutions should be avoided.

Agarose: Gel volumes and percentage
VWR offers an extensive range of high quality agaroses, for many specific applications (see
'T CHNICAL SUPPORT AND ORD RING INFORMATION').
The required volume of the gel is calculated using the following formula.
gel width (cm) x gel length (cm) x gel thickness (cm) = required volume agarose solution (ml)
The following volumes will result:

Maxi xW 'Revolution' 23 x 25 (W x L) 144 ml 288 ml 432 ml 575 ml
The optimal range of DNA fragment sizes separated by any electrophoresis experiment is dependent on
the agarose concentration of the gel. The higher the agarose concentration, the better small fragments
are separated from each other and vice versa. However, for the smallest or largest fragment lengths, the
usage of specialized agaroses or polyacrylamide gels should be considered (see table below) since a
3 % agarose solution solidifies rapidly and a 0.3 % agarose gel is very soft and difficult to handle.
Agarose content (w/v) Agarose (g) Buffer (ml) optimal separation range (kb)
0.3 % 0.3 100 5 - 30
0.5 % 0.5 100 1 - 15
0.7 % 0.7 100 0.8 - 10
1.0 % 1.0 100 0.5 - 7
1.2 % 1.2 100 0.3 - 6
1.5 % 1.5 100 0.2 - 4
2.0 % 2.0 100 0.1 - 3
3.0 % 3.0 100 < 0.1
thidium bromide
The gel may be stained during or following the run with a variety of stains for photo documentation. The
most common stain for DNA is ethidium bromide. Because of its capacity to intercalate into double
stranded nucleic acids and alter the conformation of DNA, ethidium bromide is judged to be highly
mutagenic. Therefore appropriate safety measures must be applied.
thidium bromide may be added directly to the gel before pouring it at a concentration of 0.1 to
0.5 µg/ml. However, being positively charged, ethidium bromide will migrate to the cathode during the
electrophoresis leading to uneven staining. Improved results can be obtained by incubating the gel after
the electrophoresis is finished in electrophoresis buffer containing 0.5 µg/ml ethidium bromide for 5 to
20 min. Subsequently the gel should get rinsed in electrophoresis buffer without ethidium bromide for up
to 20 min in order to reduce background signal.

Loading buffer/Sample buffer
Samples are prepared and mixed with loading buffer before applying to the prepared gel. Sample
buffers contain dyes for visibility and glycerol to provide weight to the samples. This increased sample
density ensures samples load evenly into the wells and do not float out during loading. Dyes also mi-
grate toward the anode end of the electrophoresis chamber at predictable rates allowing the gel run to
be monitored. In 0.5 x TB gels, bromophenol blue migrates at the same rate as 300 bp DNA frag-
ments and xylene cyanol approximately at the same rate as 4 kbp DNA fragments.
6 x DNA sample buffer: 0.25 % (w/v) bromophenol blue
0.25 % (w/v) xylene cyanol FF
30 % (v/v) glycerol
Molecular weight marker
Markers are run on each gel to monitor the quality of sample separation and to enable a size estimation
of specific bands. By running a known marker of a specific concentration in parallel, the DNA amount
of the unknown samples can be estimated. VWR offers an extensive range of DNA and RNA markers.
For detailed information please contact us or visit www.de.vwr.com.
TROUBL SHOOTING
Some possible solutions to potential problems are listed below. If these suggestions are unclear or un-
successful, please contact the VWR service team (see 'T CHNICAL SUPPORT AND ORD RING
INFORMATION').
Problem: Agarose leaks into casting chamber when pouring gel
Check to see if the gasket is firmly seated in the nd Gates and in the grooves on the ends of the gel
tray. Reseat gasket if necessary by removing and rinsing under warm running water, then reseat evenly
in the tray groove. Take care of an equal reseating of the gaskets in to the grooves of the nd Gates.
Problem: Bands seem to be running at an angle (Gel smiling).
Check to be sure the casting is being done on a level surface. Also confirm that the gel tray is inserted
all the way into the unit and rests on the platform for level gel casting. The voltage may be too high. Try
lowering the voltage setting on the power supply. lectrophoresis buffer may have been prepared with
wrong or expired chemicals. Perhaps no electrophoresis buffer has been used for preparing the gel
solution. Check if the stock solution of the electrophoresis buffer was diluted correctly for the preparation
of the working solution.
Problem: Samples seem to be running unevenly in certain areas.
Check that the platinum electrode wire is intact and running evenly across the base of the chamber and
up the side to the junction of the banana plug. The unit should produce small bubbles as the current
passes through. If there appears to be a break in the electrode connection, contact VWR immediately.
This problem may also be caused by regularly casting with very hot agarose gel (> 60 °C). Always cool
the melted agarose to below 60 °C before casting to avoid warping the gel tray. Warping the gel tray
will cause all subsequent gels to be cast unevenly and hence cause bad electrophoretic separation.

Instruction Manual PerfectBlue

Horizontal Maxi Gel Systems
VWR_v0617_ 10
Problem: Samples do not band sharply and appear diffuse in the gel.
Gels should be allowed to solidify completely before running. Standard agarose should solidify in about
30 minutes. If low melting point agarose is used, it may be necessary to completely solidify gels at a
cooler temperature in the refrigerator or cold room. Gels should be submerged in 3 - 5 mm of buffer to
prevent the gel from drying out, but excess buffer (> 5 mm) can cause decreased DNA mobility and
band distortion. Perhaps too much nucleic acid was applied to the wells potentially leading to
' smearing ' of the bands.
Problem: Samples are not moving as expected through the gel, remaining in the wells, running
'backwards' or diffusing into the gel.
Check to be sure that a complete power circuit is achieved between the unit and the power supply. Plat-
inum wire and banana plugs should be intact. To test, simply fill the unit with running buffer and attach
to the power supply without a gel or gel tray in the unit. The platinum wires on both sides of the unit
should produce small bubbles as the current passes through. If a complete circuit does not exist, there
will be little to no bubbles. If samples appear to run backwards through the gel or there are no bands
visible, check to be sure that the gel tray was placed in the electrophoresis chamber in the proper orien-
tation. If the orientation or polarity is reversed, the samples will run backwards or migrate off the gel.
The tray should be placed in the chamber with the comb at the edge of the tray closest to the cathode
side of the chamber.
Problem: When the comb is removed from the gel the sample well is ripped and damaged.
Always make sure to allow the gel to solidify completely and note that the gel should be submerged by
running buffer before moving the tray, unit, or removing the comb. To avoid damage to the sample
wells, gently rock the comb back and forth lightly to loosen, and then slowly pull the comb straight up
out of the gel tray. This rocking helps to avoid suction as the comb is removed.
Problem: The gel seems to run slower under the usual running conditions.
The volume of running buffer used to submerge the gel should only be between 3 - 5 mm over the gel
surface. Gel should be completely submerged to avoid the gel from drying out and to assure that a uni-
form electrical field can be generated. However, if excessive running buffer is used, the current flow
through the gel and the migration of the DNA is decreased.
