Cayman HLA-DR Monoclonal Antibody (Clone L243)

HLA-DR is a MHC Class II cell surface receptor heterodimer composed of a 33-35 kDa α chain, a ~30 kDa β chain, and a 10-30 amino acid ligand. When the heterodimer is fully combined on the cell surface of an antigen-presenting cell, such as macrophages, B cells, and dendritic cells, they present that ligand primarily to CD-4⁺ T cells. This presentation coupled with the T cell response can stimulate or suppress an antibody response to that ligand. HLR-DRs have been linked to a number of autoimmune disorders such as rheumatoid arthritis, lupus, and psoriasis as well as diabetes, hepatitis, and sclerosis among a number of others.^,,,,,, Cayman’s HLA-DR Monoclonal Antibody (Clone L243) detects HLA-DR with or without attached ligand. The predicated size of the HLA-DRα or HLA-DRβ subunits is ~29-30 kDa.
