I have a few questions regarding the products ab20436 & ab20641. Firstly, what is the difference between these two antibodies? I see that one of them says specificity for Hemagglutinin, but don't realize the difference. I would like to use this to do IHC on BOTOX TYPE A. Is it possible to use one of these antibodies for this? Also, could you kindly email me the detection limits (either in ng/ml or U/ml). Thank you so much for your help. I would really appreciate a prompt response.

Thank you for your enquiry and for your interest in our products. Clostridium botulinum neurotoxin is produced along with a group of neurotoxin-associated proteins which protect the neurotoxin from low pH and proteases of the gastrointestinal tract. The neurotoxin together with the neurotoxin-associated proteins make up the neurotoxin complex. Hemagglutinin-33 is one of the neurotoxin-associated proteins. Ab20436 is specific for C. botulinum Hemagglutinin-33. Ab20641 is specific for the C. botulinum Neurotoxin. These antibodies have not been tested in IHC. I do not have any information about BOTOX cosmetic and the detection limits have not been determined using these antibodies.
