This is a catalog of some of the 2D gel images found in a search of 2D gel databases on the web. We
will be referring to this catalog as the "2DWG" meta-database. A
meta-database contains information about data in other databases.
Data for the 2DWG is acquired by a combination of review of results
from web searching as well as
submissions by web database authors. The image files are
generally in GIF, JPEG or TIFF file formats which are suitable for Web
browsers. The table is organized by tissue type to make it easier to
find data on the same tissue from different web sources. Note, you
can search 2DWG by keywords to generate
specific subtables. This is much faster than scrolling the entire 2DWG
catalog.
The table is organized as a spreadsheet with column headings at the
top. Each row corresponds to a gel image with the fields in the row
describing the gel. The fields are defined in the Glossary of fields.
Hint: because the table is very wide, you might want to
increase the width of your browser (it looks best with Netscape). Note
also that the Miscellaneous column has information in a
smaller font. This is hard to read with 72 dots-per-inch displays, but
when printed on a 300DPI or better printer it is quite readable.
Each table entry is defined with a database name in the Image URL (eg. a
plasma gel image), DB
URL which indicates where the image came from in the web server
(eg. the page describing the plasma gel), a link to the related web organization server
URL, (eg. "ExPASy") where more information might be found on the
sample, the methods, etc. In addition, some of the servers have maps
identifying the proteins in these gel images, so the Map URL is also put
into a table entry if it exists. Otherwise, it is defined to be a raw
gel image. These may be passive or active, with the latter leading
back into protein identification databases residing on these other
servers. While most gel images have pI oriented acid to basic, some
gels are reversed. We indicate this where possible by specifying the
pIe range as increasing (acid to basic, eg. 4-8) or decreasing (basic
to acid, eg. 8-4). Since many of these databases are being improved,
you can expect these entries to change with some images being deleted
and new ones added or replaced.
This catalog will be continuously revised and edited. If you have
corrections or additions to this table, or know of published 2D Web
gels you think should be included, or have other suggestions to make
the table easier to use or more relevant, contact Peter Lemkin (Ed),
NCI/FCRDC by E-mail at
lemkin@ncifcrf.gov. You will notice that some of the fields in the
table are empty. In many of the web databases, this information is
missing or not apparent. We will be working to resolve as much of this
missing data as possible.
The NCI Flicker program is a Java application running on
your web browser for visually comparing images over the
Internet. In the future, you will be able to flicker compare a gel
image residing on your computer with one of the images in this
table.
NOTE: In the mean time, you can flicker data from this
table. However, you must go to a separate web page to pick two gels from separate lists of
gels. Alternatively, you can
flicker gels from multiple sources and any image URL. These lists
were derived from data used to construct this table.
In these databases, some images are reversed in the horizontal pI
direction and others may be reversed in Mr in the vertical
direction. Flicker will let you transform an image with the Flip
Horiz and Flip Vert operations to flip an image in the
horizontal and vertical dimensions. Because some images are on a
larger scale (either through the way they were run or because of the
scanner resolution), you might consider using the Affine
Transform option to make the regions being compared have similar
scale.
