The VIM3b monoclonal antibody recognizes CD97. CD97 is a seven-span transmembrane protein that belongs to the G-protein coupled receptor superfamily. CD97 is encoded by ADGRE5 (adhesion G protein-coupled receptor E5). CD97 is highly expressed on monocytes and granulocytes. It is also expressed on dendritic cells, T cells, B cells, NK cells, and smooth muscle cells. CD97 expression is upregulated on activated T cells. CD97 is also expressed on several cell lines including HL-60, THP-1, and K562. CD97 reportedly plays roles in leucocyte signaling, adhesion, and migration. The VIM3b antibody works in Western blotting and immunoprecipitation. The antibody recognizes proteins of 74, 80 and 89 kDa. CD55 and chondroitin sulfate are ligands for CD97.
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.
