The MIH1 monoclonal antibody specifically binds to CD274, which is also known as, B7 homolog 1 (B7-H1), Programmed cell death 1 ligand 1 (PDCD1 ligand, PDCD1L1, PDCD1LG1), or Programmed death ligand 1 (PD-L1, PDL1). CD274 and PD-L2 (CD273) are type I transmembrane glycoproteins that belong to the B7 family and serve as ligands for CD279 (Program Death 1/PD-1). CD274 is expressed on antigen-presenting cells including activated monocytes/macrophages and dendritic cells, as well as, activated T cells, and keratinocytes. CD274 is also expressed on placental trophoblasts, myocardial endothelium, cortical thymic epithelial cells, and on most carcinomas. CD274 plays an important role in regulating T cell responses. The MIH1 antibody blocks CD279 binding to CD274 and can enhance the proliferation and cytokine production of activated T cells.
This antibody is conjugated to BD Horizon™ BV605 which is part of the BD Horizon Brilliant™ Violet family of dyes. With an Ex Max of 407-nm and Em Max of 602-nm, BD Horizon BV605 can be excited by a violet laser and detected with a standard 610/20-nm filter set. BD Horizon BV605 is a tandem fluorochrome of BD Horizon BV421 and an acceptor dye with an Em max at 605-nm. Due to the excitation of the acceptor dye by the green (532 nm) and yellow-green (561 nm) lasers, there will be significant spillover into the PE and BD Horizon PE-CF594 detectors off the green or yellow-green lasers. BD Horizon BV605 conjugates are very bright, often exhibiting brightness equivalent to PE conjugates and can be used as a third color off of the violet laser.
