I want to purchase the monoclonal antibodies of VEGF, TGF-beta1, α-SMA and β-actin against rats for my research. Can you suggest the company/brand whose antibodies provide good results? I have good experience with monoclonal antibodies from Novus biological for PECAM and GAP-43. Also I had bad experience with the antibodies from Santa cruz for VEGF, PECAM, GAP-43, eNOS and TGF-beta1. Please suggest, based on your experience, the company/brand whose antibodies provide good results.
