cFluor® B515 Anti-Human HLA-DR (L243)
The L243 monoclonal antibody binds to the human HLA-DR antigen, a 36-kDa alpha heavy chain and a 27-kDa beta light chain heterodimeric cell surface glycoprotein in transmembrane major histocompatibility complex 2 (MHC II) family (1)(2). HLA-DR, also known as human leukocyte antigen DR isotype, is present on the surface of antigen-presenting cells, including B cells, dendritic cells, macrophages, monocytes and activate T cells. MHC class II regulates the immune system by playing a critical role in binding and presenting antigen-derived peptides to peptide-MHC II-specific CD4 T cells (3). The antibody was conjugated to a fluorophore and puriﬁed by afﬁnity chromatography.

Each lot of this antibody is quality control tested using flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is 5 µL per 1 million cells in a staining volume of 100 µL. If whole blood is analyzed, then use 5 µL per 100 µL. It is recommended that users titrate the antibody to obtain the optimal result for their specific application.
