HLA DRB1 Antibody (SPM289) [DyLight 488] Summary

Activated human peripheral blood mononuclear cells
Cell surface
This MAb reacts with the beta-chain of HLA-DR antigen, a member of MHC class II molecules. It does not cross react with HLA-DP and HLA-DQ. The L243 antibody recognizes a different epitope than the SPM289 monoclonal antibody, and these antibodies do not cross-block binding to each other's respective epitopes. HLA-DR is a heterodimeric cell surface glycoprotein comprised of a 36kDa alpha (heavy) chain and a 28kDa beta (light) chain. It is expressed on B-cells, activated T-cells, monocytes/macrophages, dendritic cells and other non-professional APCs. In conjunction with the CD3/TCR complex and CD4 molecules, HLA-DR is critical for efficient peptide presentation to CD4+ T cells. It is an excellent histiocytic marker in paraffin sections producing intense staining. True histiocytic neoplasms are similarly positive. HLA-DR antigens also occur on a variety of epithelial cells and their corresponding neoplastic counterparts.

FAQs for HLA-DR Antibody (NBP2-34756G). (Showing 1 - 1 of 1 FAQ).

  1. We are interested in custom labeling our antibodies to be able to integrate new markers into already existing multicolor FACS panels. We would be glad to receive pricing and general order information for anti-HLA-DRB1 and anti-HLA-DRB5. To estimate expenses for future antibody labeling orders it would be helpful to know on what basis (amount, type, etc.) the price is going to be calculated. Right now the antibodies are still in mouse ascites. Would it be possible to integrate the elution of the antibodies from the ascites before labeling as part of the service agreement?
    • While we do not generally do this kind of custom purification unless it is for very large amounts of antibody, we do have a number of kits available that may be of use to you. Since an antibody that is still in ascites can not be labeled, it will need to be purified. A list of our kits available for this can be found at the following link: AbSelect. Once the antibodies are purified, they can be labeled with any number of different colors. A list of these kits for labeling can be found at the following link: Lightning-Link.
