I am looking for IgA1 and IgA2 proteins to use as reference material in an ELISA. I was wondering how your two products 91020 and 91021 have been purified.

For IgA1, isolated from human myeloma plasma, (ab91020) and IgA2, isolated from human myeloma plasma (ab91021), we perform an initial Ammonium sulfate precipitation. After, specific affinity columns are used based on the contaminants present. For examp...

Dear Sir/Madam, we are looking for the purified human myeloma IgA1 (Ale) protein, in polymeric form if possible. We woluld like to use in ELISA as a standard or control sample. I found the product human IgA1 protein in your catalog. Is this form mainly...

Thank you very much for your interest in ab91020. We unfortunately have not done any test to check whether this protein is polymeric or not. We also do not know if the protein is glycosylated. The molecular weight of monomeric IgA is 160 kDa. Theoretic...
