Recently we established a new open access database, the zebrafish CreZoo (http://crezoo.crt-dresden.de), which contains novel CreER^T2-driver lines that express CreER^T2 in several tissues.

The database contains a helpful set of CreERT2 driver lines expressing in various regions of the developing and adult zebrafish. The lines have been generated via the insertion of a mCherry-T2A-CreERT2 in a gene trap approach or by using promoter fragments driving CreERT2. Insertions were identified and can be maintained by native mCherry fluorescence.
