Storage
Difnity RapidTips should be stored in low humidity
at room temperature (15-25 degrees Celsius). Under
these conditions, Difnity RapidTips can be stored
and used for up to 12 months without reduction in
performance or quality.

Product Use Limitations
Difnity RapidTips are intended for research use
only. Difnity RapidTip is designed for purication
of PCR solutions prior to dideoxy (BigDye) reaction
for Sanger Sequencing. RapidTip is compatible with
most universal pipettors. RapidTip has not been
tested for compatibility with detergents, mineral
oil, nor ready-to-load style PCR master mixes that
contain a density increasing compound.

Introduction
Difnity Genomics has developed an innovative new
technology that removes undesirable impurities
from PCR reactions leaving you with nothing
but puried DNA! This revolutionary technology
effectively removes dNTPs, primers, and primer-
dimers while providing up to 90% recovery of pure
DNA fragments ranging in length from 100bp to
10Kb. It dramatically reduces the amount of time
to purify and prepare PCR reactions for use in
downstream applications, such as DNA sequencing.
The RapidTip is one-tip, one-step, and one-minute
for PCR purication.

Difnity Technology Principle
The Difnity RapidTip contains everything you
need for PCR purication. The tip is lled with our
proprietary adsorption technology, which has a
differential afnity for PCR reaction components.
The impurities are removed from the solution as
it enters the pipette tip. Dispensing the solution
yields puried, high quality DNA ready to use for
downstream applications. You won’t need additional
equipment, reagents, buffers, or enzymes - only a
pipettor!

Difnity RapidTip Purication has excellent yield. Equal volumes
of untreated (-) and Difnity RapidTip treated (+) PCR product
(.5Kb, 1Kb, 2Kb) were run on a 1% agarose gel alongside
Invitrogen 1Kb Plus Ladder (L) and labeled with SybrSafe.

unpuried
Difnity RapidTip
Difnity RapidTip purication improves sequence quality.
Sequence chromatograms show improved peak quality and lower
background in Difnity RapidTip puried samples as compared to
unpuried samples.
Equipment to be Supplied by User
• PCR Sample
• Tubes to store puried DNA
• Pipettor - manual or programmable
• Standard pipette tips for liquid transfer
(if necessary)

Pipetting with the RapidTip
Careful pipetting is important to achieve effective
purication with the RapidTip. The following
pipetting guidelines will help ensure optimal results:
1. Aspirate slowly to ensure particles are dispersed
for effective mixing.
If using a manual pipettor, aspirate slowly for the
rst several cycles until the particles are completely
dispersed into the PCR sample.
If using an automated pipettor, set to aspirate on
low speed (2 of 10 or equivalent), dispense on
middle speed (5 of 10 or equivalent) and place into
manual mix mode.
2. Maintain continuous contact between the
end of the pipette tip and your sample. Avoid
disrupting the uid column with air bubbles.
3. Maintain clearance between the end of the
pipette tip and the plastic tube or well holding
sample to avoid plugging the tip during sample
mixing.
