Um, I try to stay current with bionet.drosophila & didn't see anything. But that may mean my site's expire time is shorter than the interval since my last reading of the newsgroup. If you *really* want to check whether your earlier post got out, wander into FlyBase & read the archive. >Is it >possible that there no "Delta 2-3 on the second chromosome" stock is >available? Remember that what makes "delta 2-3 (99B)" so useful is that the P element is "inexplicably" stuck there, so that tracing the dominant visible markers allows virtual 100% certainty of knowing whether delta 2-3 is present. Someone wanting to do the community (or at least Helen) a service would make a delta 2-3 derivative in which one of the P ends is crippled, and the element hopped onto each chromosome (and/or each arm) with Hobo- mediated germline transformation. It's obvious enough how. Mark -- Mark D. Garfinkel (e-mail: mg16@midway.uchicago.edu) (c) 1995; all rights reserved. Permission granted for Usenet quotation with attribution. .
