Question (54903) | Anti-PD1 antibody [NAT105] (ab52587)

Go to datasheet (ab52587)

Question

Can you tell me what the epitope of the antibody is directed against, or at least whether the antibody binds extracellular or cytoplasmic? We plan on running protein interaction studies, so we would need that information.

Answer

I can confirm that the epitope of ab52587 is extracellular, because in FACS experiments fresh, unfixed cells were used.
