1 Introduction
Thank you for purchasing the BluePippin from Sage Science. The BluePippin is an
automated preparative gel electrophoresis system.
We urge you to read this manual to familiarize yourself with the system’s capabilities and
precautions.
1.1 System Overview
There are three components to the BluePippin system:
•Instrument –The instrument includes epifluorescence detectors, an
electrophoresis power supply, an electrode array, and a Linux-based single-
board computer. The system computer is accessed by an external LCD
monitor, mouse, and keyboard. The electrode array is located in the top of the
sliding instrument cover and is not user-accessible.
•Software –System software allows the user to enter parameters that define
the DNA fragment size ranges to be collected. The software also logs
fluorescence and electrical current data which may be analyzed in a review
screen.
•Gel Cassettes –Pre-cast, disposable agarose cassettes are manufactured by
Sage Science. Cassettes are supplied in kits that contain 10 cassettes and
sufficient reagents to complete all collections. Kits have been developed to
address DNA size range collections at various size ranges. Please refer to
Section 23 for kit descriptions and ordering numbers.

1.2 How the System Works
The BluePippin systems use pre-cast and disposable agarose gel cassettes. DNA
fractions are collected by electro-elution into a buffer-filled well using a branched
channel configuration with switching electrodes. The timing of switching is determined
by measuring the rate of DNA migration with optical detection of labelled markers. The
position of the detectors beneath the gel cassette is shown in the schematic below.
1.3 Collection Strategies
Collection timing (start, duration, and end) is based on the factory calibration
settings provided with a cassette definition file, and the user-input size range settings
in software.
Note: The agarose gel matrix does not contain intercalating dyes or gel stains, sample DNA
is not viewable or monitored.
Size Selections can be undertaken using one of the following strategies:
•Labeled internal standards –Fluorescein labeled DNA internal standards are
added to samples, and run ahead of the input sample. The rates of migration of
the internal standards are used to determine the collection timing within the
sample lane. Up to 5 samples may be run per cassette.
Note: The DNA sequence of internal standards may be found at
www.sagescience.com/support, on the BluePippin resources page in the “Casssette
Guides” section.
•Labeled external marker –The fluorescein labeled DNA marker is loaded in a
single dedicated sample lane during a run. The rates of migration of the markers
are used to determine the collection timing for the remaining sample lanes.
•Timed runs –The beginning and end time of elution (size selection) is set by the
user. Neither internal standards or external markers are used.

1.4 Collection Types
The BluePippin can be programmed to size select either
targeted fractions or “High-Pass” collections. The fragment
size distributions are described below:
1. Minimum Size Distribution (“Tight” setting). The
cassette lane will collect the narrowest distribution of
fragments that is achievable given the resolution of
the agarose gel concentration within the cassette.
The distribution is Gaussian, and its range is typically
+/- 16% (CV 8%) of the median fragment size.
2. Range Size Distribution (“Range” setting). The
cassette lane will collect a distribution of fragments
between a starting base pair value and an ending
base pair value. The actual start and end fragment
sizes are typically within +/- 10% of the base pair
values input into the software.
3. High-Pass Size Distribution (uses “Range*”
setting). The cassette lane will collect all
fragments above a base pair threshold. The
method increases the average fragment length of
the collection depending on threshold value and
input DNA distribution profile. High-Pass protocols
require and external marker to be run in one lane.
*Although the cassette continues to collect until the end of the run,
an end base pair value will auto-fill in the software protocol field.
This value should be disregarded, and should not be changed by
users.

2 Keys to Successful Collections
It is recommended that users closely follow the instructions outlined in this manual until
they become thoroughly familiar with the system. The Quick Guide (included with
cassettes) provides protocol reminders, but is not intended for beginning users.
Keys to successful collections are outlined in the following sections:
•Purity of the input sample (Section 6)
•Optical Calibration (Section 9)
•Preparation of the cassettes (Section 10)
•Sample loading (Section 11)
2.1Common Misconceptions
Users should be aware of the following characteristics of the BluePippin System. These
are part of normal operation of the system, but may seem counterintuitive at first.
2.1.1 Narrowest is not always the best.
The BluePippin can produce very narrow size distributions from sheared genomic
DNA. However, narrower size distributions will necessarily mean that a smaller
fraction of the input DNA will be recovered. Users should broaden their collection
ranges if the default tight settings do not produce enough DNA for their
application.

size selections of DNA.

2.1.2 DNA undergoing elution is smaller than DNA at the detector.
The branch point between the separation and elution channels is downstream
from the detector position. Figure 2.2 shows a cassette channel to illustrate.
During normal operation, the leading edge of the DNA fraction scheduled for
elution passes the detector before the start of elution (by up to several minutes).
This offset can give rise to the impression that sample elution is late, even in runs
that are functioning properly.
Figure 2.2. An illustration of the time and base pair difference between the detector
and branch point.
2.1.3 The rate of electrophoresis is faster in the separation channel than in
the elution channel. This may cause misconceptions with regard to the timing
of broad size selections. For instance, if one sample is programmed to select
from 400 –600bp, and a second sample is programmed to select from 200 –600
bp, the narrower range will finish eluting before the broader one, even though both
elutions complete collection at 600 bp. The collections of large DNA fragments,
especially with pulsed –field protocols, can also appear counter-intuitive with
respect to timing.

and elution channels
