Hi Margaret,

I've made myc-tagged constructs driven by the maternal alpha4 tubulin and
bicoid promotors, and have had no problems with detecting the tag in any
of them.

While we're on the subject, I've nearly run out of the anti-myc 9E10
monoclonal antibody I've been using.  I've also heard that the antibody
from some suppliers is or was not very good (Im afraid I dont know which
supplier).  Can anyone recommend a good source for anti-myc antibody that
will work in embryos and on western blots?
