Question (7021) | Anti-Isopeptide antibody [81D1C2] (ab422)

Customer has purchased ab422 and needs to know the following information about this antibody: how was the antigen generated? Was cross-linking (such as BSA) involved in generating the peptide? To generate a control, what should the antibody be pre-absorbed with? Any information to help her would be greatly appreciated! Thank you in advance!
