Our Abpromise guarantee covers the use of ab93364 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB Use a concentration of 1 µg/ml. Predicted molecular weight: 41 kDa. This antibody has been tested in Western blot against the recombinant peptide used as an immunogen. We have no data on detection of endogenous protein.
ELISA 1/2000 - 1/5000.


  • Relevance
    H2-Kb belongs to the family of the mouse Major Histocompatibility Complex class I receptors. These display processed antigens from the endocytosed bacteria. MHC class I proteins can form complexes with processed antigen peptides only if the antigen is synthesized in the same cell. As a consequence, T lymphocytes can only bind to class-I-positive cells that are synthesizing the antigen (e.g. virus-infected cells).

Thank you for contacting us. We have only tested this antibody with recombinant fragment which we used as immunogen. We have not tested it using endogenous protein or lysates. This is the reason why the mouse species is predicted not tested. Abpromise does not apply to the species that are predicted. However this product is eligible for Abreview discount with mouse species. Let me know if the customer is interested in Abreview discount offer. Unfortunately we haven’t done any research on which MHC allele the C57B6 mouse displays so I would recommend doing search in literature like below  http://www.pnas.org/content/early/2011/02/02/1005342108.full.pdf I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

Thank you for contacting us. I can confirm that using this MHC Class I H2 Kb antibody ab93364 a lower band can be expected at around 40 kDa which is due to the non-glycosylated form of the protein. The upper band is the glycosylated mature protein. The predicted molecular weight and glycosylation information can be found on the SwissProt link for this protein: http://www.uniprot.org/uniprot/P01901 Unfortunately, we do not have any comments from other users since May. However, we would be very grateful if you could submit an Abreview about your experience with this product on endogenous protein samples via the online product datasheet. We always encourage customers to send their results back to us, whether positive or negative, and we make all product information available to researchers. To find out more about our Abreview system, please see the following webpage: https://www.abcam.com/abreviews I hope this information helps. Please do not hesitate to contact us if you need anything further.
