EVEG92 construct. - Fujioka, M.; Bodmer, R. (2003)
Subject: Re: FlyBase Query (cy1756) ... Question 2: EVEG92 is the one used to make the 86T, delta ES, and delta NS. The 86T construct has a \+8.6kb endpoint, and both delta ES and NS have a \+9.2kb endpoint. A wild type construct that has either endpoint gives the same expression pattern. thanks, rolf On Wed, 5 Feb 2003, Chihiro Yamada wrote: > Dear Dr Bodmer, > > I'm currently curating your paper for FlyBase: > > Han et al. 2002, Dev.

J48 and J43 are insertion lines of the delta ES and delta NS construct, respectively (+9.2kb endpoint). In fact, we tested another delta ES insertion line, J49, which also abolished mesodermal expression, as J48. I hope this clarifies the issue. thanks, rolf On Fri, 7 Feb 2003, Chihiro Yamada wrote: > Dear Rolf, > > Thanks for your prompt reply. > > > Question 2: > > EVEG92 is the one used to make the 86T, delta ES, and delta NS.
