Tg(Thy1-PTGS2)300Kand

The transgene construct contains the entire 1.8 kb human COX-2 (PTGS2; prostaglandin-endoperoxide synthase 2 or PGE2) open reading frame sequence inserted into the 8.2 kb Thy-1 expression cassette. This construct was injected into the male pronuclei of C57BL/6J cells. No founder lines were provided in the original reference but lines 300, 303, and 316 were characterized in subsequent publications. Mice from founder line 300 were found to have an approximately 10-12-fold increase in PGE2 expression. (J:72034)
