anti-gastrin antibodies

[Mike Gruidl]

Hi all:

I am looking for antibodies against human gastrin, a small peptide 
hormone.  We bought one from Sigma, it is made against a synthetic 
peptide derived from the first ten amino acids.  Initially results were 
not convincing on formalin fixed parafin sections. We are currently 
repeating the immunostaining.  Northern blots were weakly positive and 
the controls responded correctly.  So if anyone knows of  a commercial 
source of another antibody or if they have a non-commercial stock they 
would be willing to part with a small sample I would be very 
appreciative.

thanks
