Beschreibung: HLA DR, like other MHC class II molecules, is a transmembrane glycoprotein composed ofan alpha chain (36 kDa) and a beta chain (27 kDa). It is expressed primarily on antigenpresenting cells such as B lymphocytes, monocytes, macrophages, thymic epithelial cellsand activated T lymphocytes. Three loci, DR, DQ and DP, encode the major expressedproducts of the human class II region. The human MHC class II molecules bindintracellularly processed peptides and present them to T helper cells. They therefore havea critical role in the initiation of the immune response.

Spezifität: The antibody MEM-12 recognizes common epitope on human HLA-DR which is dependenton the association of alpha and beta chains. DR is the isotype of human MHC Class IImolecules expressed on antigen-presenting cells (APC, Dendritic cells, B Lymphocytes,Monocytes, Macrophages). Species: Human. Others not tested.
