Catalog number BNUM2281-50
Price for BNUM2281-50
Size / count 1x 50 µL
This MAb reacts with a 28 kDa chain of HLA-DRB1 antigen, a member of MHC class II molecules. It does not cross react with HLA-DP and HLA-DQ. The L243 antibody recognizes a different epitope than the LN3 monoclonal antibody, and these antibodies do not cross-block binding to each other's respective epitopes. HLA-DR is a heterodimeric cell surface glycoprotein comprised of a 36 kDa alpha (heavy) chain and a 28 kDa 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. Primary antibodies are available purified, or with a selection of fluorescent CF® Dyes and other labels. CF® Dyes offer exceptional brightness and photostability. Note: Conjugates of blue fluorescent dyes like CF®405S and CF®405M are not recommended for detecting low abundance targets, because blue dyes have lower fluorescence and can give higher non-specific background than other dye colors.

If you’re outside the EU, UK, or USA, you’re responsible for customs clearance and any related taxes or fees. We provide the standard import documents, such as the Commercial Invoice, Packing List, and Airway Bill, in advance, so let us know early if your customs office needs anything additional for this specific product.
The formulation or storage buffer is listed on the product datasheet. If you require a carrier-free or custom formulation, contact us before ordering, as this may involve a made-to-order production timeline.
A starting IHC dilution range is listed on the datasheet, but should be optimized for your specific tissue type and staining protocol.
