Question
Answer

Thank you for contacting us.

Unfortunately we have not determined which specific HLA-A2 allele(s) this clone binds. However, it is clear from the paper you kindly provided that the clone binds HLA-A201. Unfortunately, we currently do not have any empirical data to indicate if this clone is specific just to the HLA-A201 allele or if detects other alleles.

Question
Answer

Thank you for filling out the questionnaire. Your protocol looks good. Do you incubate the cells with the antibody in the dark? FITC is sensitive to photo-bleaching. The only other recommendation I can make would be to try BSA instead of FBS for blocking, in case there are interactions with fetal serum proteins other than BSA that are blocking binding of the antibody to the HLA A2. The PBS-only control is a good idea but you may be losing the antibody to hydrophobic interactions with the tube you incubate in when you leave out blocking protein. The BSA is admittedly a long-shot solution. If you feel photo-bleaching is not a problem, then I can send you a free-of-charge replacement vial, or a refund or credit. Let me know what you would like.
