HLA-DR Antibodies
Human Leukocyte Antigen -DR isotype (HLA-DR) is a major histocompatibility complex (MHC) class II molecule expressed by antigen presenting cells that functions in immune system response. HLA-DR molecules are heterodimers consisting of a 34 kDa alpha chain subunit and an approximately 30 kDa beta chain subunit. Our catalog includes a 5-star reviewed antibody featured in 29+ publications. Browse our extensive inventory for recombinant monoclonal antibodies, monoclonal antibodies, and HLA-DR-conjugated antibodies. Validated research applications for our HLA-DR-antibodies include CyTOF-ready, ELISA, Flow Cytometry, ICC, Immunofluorescence, IHC-Frozen, IHC-Paraffin, Immunoprecipitation, Radioimmunoassay, and Western Blot. Our HLA-DR antibodies are reactive in Human, Canine, Primate, and more. Each HLA-DR antibody is fully covered by Novus’ Guarantee+. Choose the anti-HLA-DR antibody best suited for your research needs by viewing the technical details, images, references, reviews, and related products.
