Hi, I have to see some protein-protein interaction for which I am using the yeast two hybrid system. After constructing the fusion GBD and GAD constructs (in pGBD C1 and pGAD C1 vectors) I want to verify the expression by western blotting using anti GBD and anti GAD antibodies.So, my question is -can any body tell me a source of antibodies against the Gal binding domain(GAD) and Gal activation domain (GBD) that I can use for the above mentioned purpose?
