	    I need to  to ask you a fovor. We need a Drosphila cosmid
library. The one that we have here in the lab is dead. I am desperate
trying to find someone that has the cosmid library prepared by John Tamkum.
We sent an e-mail to this guy but he didn't reply.The advantage of this
library is that the vector has already a P element and the gene white. This
is great because you can use your clones directly to prepare your
transgenic flies.I hope you could help me somehow.

Thanks in advance
