2. Overview of Raw 2-D Gel Electrophoresis
Raw 2-D electrophoresis is a method for separating proteins and nucleic acids in a
sample into a two-dimensional pattern of spots in a gel. It combines the techniques of
isoelectric focusing (IEF) with SDS-polyacrylamide gel electrophoresis (SDSPAGE). Since these two separation methods rely on independent properties of
proteins—chemical and physical—this procedure can resolve complex biological
samples with a high degree of specificity and accuracy. The resolved proteins and
polypeptide fractions can be then identified by their molecular weights and charges
(as indicated by their locations in the Raw 2-D gel), as well as by their differential
expression in different samples, proximity to other spots, intensity, etc.
Raw 2-D electrophoresis involves two sequential separations of a sample in
perpendicular directions. The IEF dimension is run first, in tube gels or on
immobilized pH gradient (IPG) strips. After focusing, the tube gel or strip is placed
on top of an SDS-PAGE slab gel and electrophoresed. This technique can resolve
thousands of prot ein spo ts in a sin gle sa mple; these pr oteins can then b e visualized by
metabolic radiolabeling or a variety of staining methods.
Proteomics Applications
Proteomics is the study of protein expression and regulation in cells, tissues, and
entire organisms. Sev eral thous and proteins are expressed at any given moment in an
organism; at the cellular level, dozens of proteins may be expressed and regulated in
fractions of a second.
Two-dimensional gel electrophoresis is a a cornerstone in the study of how proteins
are expressed, regulated, and modified throughout living systems. Developed almost
a quarter of a century ago, Raw 2-D gel techno logy remains one of the most po werfu l
techniques for resolvin g comp le x mixt u res of p rot eins . The technology has improved
significantly over the past several years, with the advent of IPG strips and simplified
gel running techniques, large-format and cyber gels that allow for greater pH range
and specificity, and new stains and staining techniques. In addition, mass
spectrometry now allows for peptide mass fingerprinting of very small amounts of
protein isolated from gels.
Using a combination of these techniques, pharmaceutical companies can now use
Raw 2-D technology for high-throughput screening of drug compound candidates
using protein targets; research laboratories can study large-scale changes in protein
x

expression; and companies and institutions can cross-identify and catalog hundreds of
thousands of protein specie s at the cellular level. This prov ides an ex cellent technique
for the study of differential gene expression under various growth conditions. Since
the expression and regulation of indivi dual pro teins can be detected,Raw 2-D gels are
an indirect way to monitor gene activity. They allow for the investigation of
quantitative as well as qualitative changes in cellular protein expression.
The environmental conditions of a cell can be changed in order to determine optimal
growth conditions as well as monitor the cell’s response to different stresses.
Environmental conditions that can stress the cell include changes in temperature, pH,
and nutrient availability. Some examples of the chemical stresses that can be placed
on a cell include drug and hormone treatments. Since protein structure and function
are the direct result of gene expression, the loss or change of a protein as detected by
a Raw 2-D gel can be extrapolated back to events occurring at the DNA level.
Many questions encountered when genes are inserted and express ed in bacteria, yeast,
and other cell types can be answered with Raw 2-D analysis: Is the cell making the
protein? Is the cell’s progeny making the protein? Is the protein being made but not
secreted? Have mutations occurred?
Medical Applications
Raw 2-D gels can also have important application s in medical research. For example,
this technique can be used to verify the presence of specific protein markers that are
linked to genetic diseases and disease states. Used in conjunction with other tests,
Raw 2-D gels can be part of medical screening procedures associated with mutations
and teratology linked to genetic damage.
Growth factors are being studied for their role in the regulation of cell growth. Raw 2D gels can be used to evaluate quantitative and qualitative changes in cellular proteins
in response to growth factor stimulation.
Raw 2-D gels allow the visualization of proteins whose expression is altered as the
result of cell transformation, introducing oncogenes into the host genome.
Assessment of phosphorylation, sulfation, or other secondary modifications could
reveal functional protein pathways affected by on cogene expression . This informatio n
could contribute to a better understanding of cell growth and regulation.

PDQuest User Guide
Sample Experiments
Valuable information can be learned by exposing cells to a set of specific
experimental conditions and subsequently examining their biological response.
A preliminary in vitro ex peri men t that is us eful when b e ginning Raw 2-D gel work i s
to radiolabel a cell’s proteins to steady-state with
these proteins will help to determine the commonly expressed proteins in the cell
under normal conditions.
Subsequently, other amino acids such as 3H-leucine, 3H-proline, 3H-lysine, etc., can
be used to radiolabel the proteins to steady-state. This will label any proteins that do
not contain methionine and were, therefore, not detected in the first experiment, and
will provide preliminary information on the amino acid composition.
Other experiments complementary to Raw 2-D gels include: cell fractionation
procedures, and post-translational mod ifications (phosphorylation, methylation, etc.).
Data from these experiments can be added to a database, accumulating information
about these proteins.

1. Introduction
1.1 Overview of PDQuest
PDQuest is a software package for imaging, analyzing, and databasing Raw 2-D
electrophoresis gels.
The software runs in a Windows or Macintosh environment and has a graphical
interface with standard pull-down menus, toolbars, and keyboard commands.
PDQuest can acquire images of gels usi ng any of several Bio-Rad imaging syst ems.
An image of a gel is captured using the controls in the imaging device window and
displayed on your computer screen. T he scanned gel can then b e cropped, rotated , etc.
using the image editing controls.
Spot Detection, Analysis and Databasing
With Automated Spot Detection and Matching you can select the gels you want to
anlayze, detect spots of interest, create a MatchSet, and match gels all from one
dialog box. The Spot Detect ion Wizard guides you through the process of identifying
and quantifying the spots in the gel image.
After detection, gels in the same experimental series are placed in a MatchSet for
comparison, statistical analysis, and databasing. Histograms allow you to quickly
compare the quantities of the same spot in all the gels in a matchset. Spots can also be
compared qualitatively, organized into user-defined sets for further analysis, and
annotated and databased for easy identification. Spots from differen t experi ment al
series can be organized and compared in high-level matchsets.
PDQuest can be used to simultaneously analyze thousands of spots on hundreds of
gels. Data can be exported to other applications such as spreadsheets for further
analysis.

PDQuest User Guide
Mass Spec Analysis
PDQuest is part of Bio-Rad’ s ProteomeWorks protein analysis package, and controls
Bio-Rad’s ProteomeWorks Spot Cutter. You can cut spots from gels or membranes
using PDQuest, digest them, and perform advanced protein analysis using
MicroMass’ s mass spectrometry instruments and software. Data from MicroMass can
then be imported back into PDQuest to be included in spot annotations.
And More...
Scan files acquired in PDQuest can be analyzed using other Bio-Rad Discovery
Series software applications, such as Quantity One or Diversity Database. Scans can
be converted into TIFF format for easy compatibility with other applications.
1.2 Digital Data and Signal Intensity
The Bio-Rad imaging devices supported by PDQuest are light and/or radiation
detectors that convert signals from biological samples into digital data. PDQuest then
displays the digital data on your computer screen, in the form of gray scale or color
images.
A data object as displayed on the computer is composed of tiny individual screen
pixels. Each pixel ha s an X an d Y coo rdinate, an d a valu e Z. Th e X and Y c oordi nates
are the pixel’s horizontal and vertical positions on the image, and the Z value is the
signal intensity of the pixel.

Fig. 1-1. Representation of the pixels in two digitally imaged spots in a gel.
For a data object to be visible and quantifiable, the intensity of its clustered pixels
must be higher than the intensity of the pixels that make up the background of the
image. The total intensity of a data object is the sum of the intensities of all the pixels
that make up the object. The mean intensity of a data object is the total intensity
divided by the number of pixels in the object.
The units of signal intensity are Optical Density (O.D.) in the case of the GS-700 an d
GS-710 densitometers, the Gel Doc and ChemiDoc with a white light source, or the
Fluor-S and Fluor-S MAX MultiImagers with white light illumination. Signal
intensity is expressed in counts when using the Personal FX or FX, or in the case of
the Gel Doc, ChemiDoc, Fluor-S, or Fluor-S MAX when using the UV light source.

Introduction
Sp ot Identifica tion
Now you are ready to identify the spots in the gel. The Spot Detection Wizard
automates the process of selecting the proper spot detection parameters for your gels.
Using the Wizard, you select the parameters, study the results of spot detection, then
adjust the parameters until you have identified all spots of interest in your gels.
When spots are detected in PDQuest, the original gel image is filtered and smoothed
to clarify the spots, then three-dimensional Gaussian spots are created from the
clarified spots. The end result is three separate images: the original unaltered scan (2D Scan), the filtered and processed scan (Filtered image), and a synthetic image
containing the Gaussian spots (Gaussian image).
2-D Scan Filtered Image Gaussian I mage
Fig. 1-3. Images created during spot detection.
All spot matching and analysis in PDQuest are performed on Gaussian spots.
What Are Gaussian Spots?
Fuzzy, streaked, or overlapping spots in a 2-D gel can be difficult to accurately
distinguish and quantify. Because the image profile of an ideal spot confirms to a
Gaussian curve, PDQuest uses Gaussian modeling to generate spots that can be
precisely identified and quantitated.
A Gaussian spot is a three-dimensional representation of an original scanned spot.
Gaussian curves are fitted to the scanned spot in the X and Y dimensions, and then
additional modeling is performed to create the final Gaussian spot.
Using Gaussian modeling, you can accurately quantitate overlapping spots, spots in
gel streaks, and multiple spots in dense clusters.
1-5
PDQuest User Guide
Matching and Editing
After you have detected the spots in a gel or set of gels, you are ready to create a
matchset. A matchset is composed of the Raw 2-D, Filtered and Gaussian images of
the gel(s) in an experiment.
In a matchset, the protein spots from the different gels are matched to each other and
are included in a synthetic image called a matchset standard. The standard in cludes all
the information about the spots in the matchset.
As you match the spots in a matchset, you will correct the results of autom a tic spot
detection by comparing the Gaussian spots with the original spots in the Filtered
image.
Data Analysis
PDQuest provides a variety of analytical tools to help you determine which spots are
statistically and scientifically meaningful.
You can normalize the spot quantities in different gels for more accurate comparison.
You can define replicate groups of duplicate gels. You can create groups of spots that
are quantitatively, qualitatively, and statistically sig nificant using analysis sets. You
can compare the similarity of gels using scatter plots, and review the quantitation of
individual spots usin g the Sp ot Review Tool.
Many of these tools are interactive with the matchset, so you can study the actual
spots in the images as you review their quantities and other data.
You can create high-level matchsets to compare the results of different experiments.
And the powerful annotation tool allows you to annotate your spots, link to Internet
protein databases or other files, and create HTML pages of spot data.
Spot Cutting and Mass Spec Analysis
PDQuest is part of Bio-Rad’s ProteomeWorks protein analysis package, and controls
Bio-Rad’s ProteomeWorks Spot Cutter. You can cut spots from gels or membranes,
digest them, and perform advanced protein analysis using MicroMass’s mass
spectrometry instruments and software. Data from MicroMass can then be imported
back into PDQuest to be included in spot annotations.
