Bulk anti-human HLA-DR antibody (L243)
ichorbio’s anti-human HLA-DR antibody (L243) is manufactured in a cGMP compliant, ISO Quality Standard 9001:2015 facility. ichorbio’s low endotoxin antibodies have half the endotoxin of comparable antibodies from our competitors at less than 1.0 EU/mg. If ichorbio’s low endotoxin antibodies are not low enough we also offer ultra low endotoxin antibodies which have even less endotoxin (<0.75EU/mg) at an even higher purity (98% versus 95%). ichorbio: the best antibodies for in vivo research.
ichorbio’s L243 in vivo antibody is available in the following bulk sizes:
1mg, 5mg, 25mg, 50mg and 100mg
ichorbio regularly manufactures multi-gram amounts of our anti-HLA-DR L243 clone – please contact us for pricing.
Major Histocompatibility Class II, MHC class II, HLA-DR Monomorphic
Anti-human HLA-DR antibody (L243) recognizes/reacts with the HLA-DR antigen, a member of MHC class II molecules. It does not cross-react with HLA-DP and HLA-DQ
This monoclonal antibody was purified using multi-step affinity chromatography methods such as Protein A or G depending on the species and isotype.
The HLA-DR antigen is present on B-lymphocytes, activated T-lymphocytes and activated natural killer (NK) lymphocytes. This antigen is also expressed on monocytes, macrophages, human progenitor cells and B-cell lymphomas.
HLA-DR is a heterodimeric cell surface glycoprotein comprised of a 36 kD (heavy) chain & a 27 kD (light) chain. It is expressed on B cells, activated T cells, monocytes/macrophages, and dendritic cells. HLA-DR is critical for efficient peptide presentation to CD4+ T cells. Clone L243 binds a conformational epitope on HLA-DRalpha which depends on the correct folding of the Aβ heterodimer.
