Thank you for your email. I'm replying on behalf of Charlotte who is currently away from the office. To clarify the concentration of this product, the concentration of the anti-PSA IgG is 100 ug/ml. This antibody has not been affinity purified (the purity of the antibody is IgG fraction) and the 1.5 mg/ml is the concentration of all the IgGs present. The 1.5 mg/ml information on the datasheet is misleading and I have removed it. I apologize for any confusion. I hope this helps, please contact us again if you have any additional questions.

Thank you for your enquiry. Following correspondence with the lab I have determined that the total protein conc. of this antibody is 1.5 mg/ml but the IgG conc. is 100 ug/ml. Please can you confirm that you mean 100 ng/ml and not 100 ug/ml.

Thank you for your email. I can't tell you the name of the originator of ab9537 as that information is proprietary. I double-checked ab403 and ab2218, and both of these do not contain BSA or other proteins in the storage buffer. Ab403 consists of preservative: 0.1% Sodium Azide, and constituents: sodium chloride, citrate / phosphate. pH 6.0. Ab2218 consists of preservative: 15mM sodium azide, and constituents: PBS. pH 7.4. Please contact us again if you have any additional questions or concerns.
