The 10E9.6 monoclonal antibody specifically binds to the 97-110 kDa cell surface glycoprotein E-selectin (CD62E), also known as endothelial-leukocyte adhesion molecule-1 (ELAM-1), which is expressed on endotoxin- or cytokine-stimulated mouse endothelial cells. A suspension of TNFα stimulated mouse brain capillary endothelioma cells, from the cell line bEnd.3, was used as the immunogen. The epitope recognized by mAb 10E9.6 has been mapped to the first and/or second complement regulatory protein repeat domains of E-selectin. The 10E9.6 antibody has been reported to block binding of a monocyte cell line to E-selectin in vitro and to block neutrophil migration in BALB/c, but not C57BL/6 mice. It has no effect on leukocyte rolling in TNFα-treated mouse venules or on in vitro adhesion of myeloid cells to E-selectin. Studies have demonstrated that Cutaneous Lymphocyte Antigen (CLA), recognized by mAb HECA-452 (Cat. no. 555946), may be a ligand for CD62E.
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.
