Mfr.No.	V2589SAF-100UG
Clonality	Monoclonal (mouse origin)
Description	This mAb reacts with a 28kDa chain of HLA-DRB1 antigen, a member of MHC class II molecules. It does not cross react with HLA-DP and HLA-DQ. HLA-DR is a heterodimeric cell surface glycoprotein comprised of a 36kDa alpha (heavy) chain and a 28kDa beta (light) chain. It is expressed on B-cells, activated T-cells, monocytes/macrophages, dendritic cells and other non-professional APCs. In conjunction with the CD3/TCR complex and CD4 molecules, HLA-DR is critical for efficient peptide presentation to CD4+ T cells. It is an excellent histiocytic marker in paraffin sections producing intense staining. True histiocytic neoplasms are similarly positive. HLA-DR antigens also occur on a variety of epithelial cells and their corresponding neoplastic counterparts. Loss of HLA-DR expression is related to tumor microenvironment and predicts adverse outcome in diffuse large B-cell lymphoma.
Formulation	1 mg/ml in 1X PBS; BSA free, sodium azide free
Host	Mouse
Immunogen Region	Activated human peripheral blood mononuclear cells were used as the immunogen for the anti-HLA-DRB1 antibody.
Isotype	Mouse IgG2b, kappa
Species Reactivity	Human
Note	Optimal dilution of the anti-HLA-DRB1 antibody should be determined by the researcher.1. Staining of formalin-fixed tissues is enhanced by boiling tissue sections in pH 9 10mM Tris with 1mM EDTA for 10-20 min followed by cooling at RT for 20 min2. The prediluted format is supplied in a dropper bottle and is optimized for use in IHC. After epitope retrieval step (if required), drip mAb solution onto the tissue section and incubate at RT for 30 min.

Uniprot	P01911

Format	Purified
Purity	Protein G affinity chromatography
Storage	Store the anti-HLA-DRB1 antibody at 2-8oC (with azide) or aliquot and store at -20oC or colder (without azide).

Applications	WB, FACS, IF, IHC-P
Description	Flow cytometry: 1-2ug/million cells,Immunofluorescence: 1-2ug/ml,Weste blot: 1-2ug/ml,Immunohistochemistry (FFPE): 0.25-0.5ug/ml for 30 min at RT
