Overview

  • Product name
    Anti-HLA Class I antibody [MEM-147]
    See all HLA Class I primary antibodies
  • Description
    Mouse monoclonal [MEM-147] to HLA Class I
  • Host species
    Mouse
  • Specificity
    Reacts with all human classical MHC Class I molecules in native cell-surface forms. Positive in immunoblotting with many (not all) MHC Class I allelic forms (e.g. it recognizes native HLA-A2 in cytofluorometry and immunoprecipitation but not in Western blotting). Positive in Western blotting (non-reducing conditions) with most HLA-B and HLA-C molecules, but not HLA-A. Epitope specificity is very similar to classical antibody W6/32 (ab7855).

    Overlay histogram showing Jurkat cells stained with ab9090 (red line). The cells were fixed with 4% paraformaldehyde (10 min) and incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab9090, 1µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive result in 80% methanol (5 min) fixed Jurkat cells used under the same conditions.
    Please note that Abcam do not have any data for use of this antibody on non-fixed cells. We welcome any customer feedback.

I am looking for an antibody for FACS analysis that recognizes HLA-A, B or C but not the B2 microglobulin portion of the HLA Class I antigen. I need to know if the actual HLA-A, B or C molecule is expressed on the outside of the cell and if the anitbo...

Thank you for your enquiry. For this particular antibody, we unfortunately do not have this information. Our source for ab9090 has also said that they think that a pan MHC antibody that recognizes only the free heavy chains on the surface (where it is ...

I am looking for an anti HLA classI monoclonal antibody of the IgM isotype. Please, could you let me know if there is one IgM isotype among yours ab 2217 (MEM 123), ab 9090 (MEM 147) or ab 3975 (MEM 81).

Thank you for your email. Ab2217 is isotype IgG3; ab9090 is isotype IgG1; and ab3975 is isotype IgG1. You may also find the isotype information on our online datasheets. If you have any additional questions, please contact us again.

Customer is interested in using this antibody (ab9090) in IP and WB, and would like to know if it cross-reacts with HLA-G or whether it blocks any other HLA G antibodies. Any information would be greatly appreciated. Thanks!

The supplier gave me the following information regarding your question. If you have any additional questions, please contact us again. The antibody MEM-147 (ab9090) does not react with HLA-G1 overexpressed in transfectants. It can be used for IP ex...

I'm interested in a marker for human cells - identifying cells implanted into rodent brains viewed immunohistochemically. The human cells implanted may take on any phenotype so we are not able to rely simply on something like a human specific anti-ner...

Interesting question, but I'm afraid that we are unable to offer any suggestions. Please let us know if you find a suitable target.

Hi Abcamteam ! Is this antibody useful for blocking experiments in an MLTC ? Best regards from Mainz Kai Kronfeld
