    Mouse monoclonal [MEM-123] to HLA Class I

  • 由来種

    Mouse

  • 特異性

    This antibody reacts with all human classical MHC Class I molecules in native cell-surface forms as well as with human HLA-G cDNA transfected cells. This antibody completely blocks the binding of pan MHC antibody (ab7855) but does not block binding of anti-HLA-G(ab7758/7904) to surface-expressed HLA-G.

Question

I am currently trying to find an anti-human-HLA class I antibody that does not bind to human HLA-G. At the moment, I have an anti-human-HLA-A/B/C antibody that does bind human HLA-G and as I am wanting to do some double staining, this is skewing my experiments. Do you know if any of your anti-human-HLA class I antibodies do not bind human-HLA-G? If you don't know, would it be possible for you to send me a sample of an APC-conjugated anti-human-HLA class I antibody for me to test?

Answer

Thank you for contacting us.

To our knowledge our HLA Class I antibodies have not been tested to not detect HLA-G. I did find that our anti-HLA Class I [MEM-123] antibodies have the following specificity:

This antibody reacts with all human classical MHC Class I molecules in native cell-surface forms as well as with human HLA-G cDNA transfected cells. This antibody completely blocks the binding of pan MHC antibody (ab7855) but does not block binding of anti-HLA-G (ab7758/7904) to surface-expressed HLA-G.

While many of the HLA Class I products are created from tissue preparation and have not been epitope mapped, I have contacted the lab to determine whether the peptide immunogen used to create ab134743 is from a region which differs from HLA-G. I will let you know the result of that query.

Because we carry over 70,000 products, it isn't feasible for us to keep small sample sizes of our products. We are happy to reassure our customers that all of our products are covered by our Abpromise, which guarantees that the product will work in the applications and species specified on the datasheet, or we will offer a replacement, credit, or refund within 6 months of purchase.

I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

Question

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).

Read More
Answer

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.

Question

Dear sir/madam, I am looking for a monoclonal antibody raised against human MHC class 1 molecules other than W6/32. The antibody has to be reactive towards conformational recombinant MHC molecules but not towards non-native forms. Could you tell me whether or not MEM-123 fits this description? Many thanks,

Read More
Answer

This antibody is reactive only with the native form of the protein but not with the denaturated form (i.e it is not suitable for Western blotting). It is not known if it differs from W6/32 significantly. However, there are some data suggesting that W6/32 blocks the FITC-labelled form of this antibody.
