Antibody to rabbit TGF beta

[Mark Rekhter]

Please, help!
I am looking for an antibody crossreacting with the rabbit TGF beta. 
Ideally, it would be nice to have several antibodies to discriminate TGF 
beta 1, 2, and 3. I realized that the vast majority of antibodies against 
TGF beta are the rabbit policlonals, unfortunately. However, there are 
some sheep, chicken, and turkey polyclonals, as well as mouse monoclonals 
on a market. As a rool, vendors do not have a little idea about 
crossspecies reactivity of their products. If you have any information, 
please let me know. Your help will be greatly appreciated.
Thanks in advance. Mark
