The 2DWG meta-database of 2D-PAGE protein gel images found on the Web. A meta-database contains information about data in other databases. The 2DWG database is a organized as a spreadsheet table with each gel image represented by a row. Data for each gel entry includes tissue, species, cell-line, image URL, database URL, gel protocol, organization URL, image properties, map URL if it exists, etc. It uses a simple database search engine dbEngine to access selected rows of gels in the full 2DWG table. The search expression is made up of combinations of words (i.e. terms) contained in the database. The search is conducted on each row with that row reported if a match is found. Once a search results table is generated, it is possible to visually compare, using Flicker, two images from the table or one from the table and one from an arbitrary web address.

Search the 2DWG Database

The database may be searched to find rows matching a combination of search terms present in that row.

Search the 2DWG Database by specifying search terms below in a search expression. A term is a word without spaces and is case-independent. Each term is delimited by either AND or OR connectives (but not both). [You may use '+' in place of 'AND'.] This search expression is then used to perform the search. Press the Return or Enter key after entering the search expression. You may also press the Search button to start the search.

Note that Map image entries are those where there is an active or passive spot map identifying proteins in the associated Web database. Raw image gets just raw gels (which may be of a lower quality) and No map or raw restriction gets all of the gels for that tissue type. Note that some tissues don't have map images. So depending on which map search restriction is set, you may retrieve no database entries. If this is the case, back up to change the map restriction and try again. Also If you are using the OR connective in the search expression, you must set the "No map or raw restrictions" button.

restrict by gels with : Map image, Raw image, No map or raw restrictions
Search expression

    Eg. type "human AND ventricle" in the Search expression field 
    to find all 2DWG database gel images with this constraint.

Alternatively, you can select one tissue or fluid type in the scrollable menu below. Remember to set the desired map/raw button above before pressing Search.
