up to date database of transgenic mice - (Jan/04/2010 )

Hello

I wonder if anybody knows an online database (or another source of information) that contains up to date information about transgenic mice. All the databases that I have found so far seem to be incomplete and/or outdated.

greets

try the nucleic acids research on-line database of databases http://www.oxfordjournals.org/nar/database/a/
