Specifications

Product Data

• Clone Name: MEM-267
• Applications: FC
• Recommended Dilution: Flow Cytometry analysis: 5 µg/ml.
• Reactivities: Human
• Host: Mouse
• Isotype: IgG2b
• Clonality: Monoclonal
• Immunogen: Purified, insoluble DR1 beta chain (DRB1*0101) expressed in E. coli inclusion bodies.
• Specificity: Reacts with immature dendritic cells that express empty cell surface MHC molecules, but not cells that express predominantly peptide loaded forms; reacts specifically with the empty but not peptide-loaded form of HLA-DR1.
  This antibody specifically binds to the empty but not peptide-loaded form of HLA-DR1. DR is the isotypes of human MHC Class II molecules expressed on antigen-presenting cells (APC; dendritic cells, B lymphocytes, monocytes, macrophages).

• Background: HLA-DR1 belongs to the HLA class II beta chain paralogues. The MHC Class II molecule is a heterodimer consisting of an alpha (DRA) and a beta chain (DRB), both anchored in the membrane. It plays a central role in the immune system by presenting peptides derived from extracellular proteins. MHC Class II molecules are expressed in antigen presenting cells (APC). The beta chain is approximately 26-28 kDa. Within the DR molecule the beta chain contains all the polymorphisms specifying the peptide binding specificities. Hundreds of DRB1 alleles have been described and typing for these polymorphisms is routinely done for bone marrow and kidney transplantation.
• Synonyms: MHC class II antigen DRB1, DR1, DR-1
