we are having the same problem with the 5' end of our gene. if it doesn't fall
out soon with standard PCR and nuclease protection we will try one of the
advanced RACE kits. i have seen 2 others besides clontech, invitrogen and
if anyone has any other ideas or insights into which race kit is best, i would
like to know.
