Thank you very much for your interest in our products. ab89191 (Anti-CD32 antibody [MM0270- 3L1]) from our catalogue was raised using CD32b extra cellular domain and reacts with both CD32a and CD32b. Unfortunately, it was not specifically tested if it reacts with CD32c. But since the CD32c and CD32b extra cellular domains are identical, we assume that it should also recognize CD32c. This antibody is tested and guaranteed to work in WB with human samples by our Abpromise guarantee. Please follow this link to review the datasheet of ab89191: Click here (or use the following: https://www.abcam.com/CD32-antibody-MM0270-3L1-ab89191.html). I am also happy to confirm that ab41899 (Anti-CD32 antibody [AT10]) binds to the extracellular region of CD32 and reacts with all isoforms of CD32, as described in Sandilands, G.P. et al. (2007) Immunol. 91: 204-211. Furthermore, clone AT10 has been shown to block CD32 and displace any antigen (IgG) that is bound to the receptor. This antibody is not tested and guaranteed for WB. If you would like to test this antibody in WB you might be eligible for our Abreview testing discount program. I hope this information was helpful. Please do not hesitate to contact me again with any further questions or if you would like to test ab41899 in WB.

Thank you for your enquiry. I can confirm the following details which I have obtained from the laboratories: ab41899 CD32 antibody: Unfortunately, we do not have a specific protocol for the use of this product in blocking experiments, this application is supported based upon the literature. There are a number of articles which may be helpful to you, I have listed some examples below: Larsson M, Berge J, Johansson AG, Forsum U. Human dendritic cells handling of binding, uptake and degradation of free and IgG-immune complexed dinitrophenylated human serum albumin in vitro. Immunology. 1997 Jan;90(1):138-46.

PMID: 8759741 I hope this information is helpful. Should you have any further questions, please do not hesitate to contact us again.

As far as I am aware, there has not been a study formally identifying the minimal epitoperecognised by this antibody. However, there is some information on the epitope recognised in the original paper describing the antibody: Greenman J, Tutt AL, George AJ, Pulford KA, Stevenson GT, Glennie MJ. Characterization of a new monoclonal anti-Fc gamma RII antibody, AT10, and its incorporation into a bispecific F(ab')2 derivative for recruitment of cytotoxic effectors. Mol Immunol. 1991 Nov;28(11):1243-54. Metes D, Ernst LK, Chambers WH, Sulica A, Herberman RB, Morel PA. Expression of functional CD32 molecules on human NK cells is determined by an allelic polymorphism of the FcgammaRIIC gene. Blood. 1998 Apr 1;91(7):2369-80. I hope that is of some help to you,
