The TLD-3A12 antibody specifically recognizes CD31, also known as PECAM-1 (platelet endothelial cell adhesion molecule). CD31 is a ñ130 kDa integral membrane glycoprotein, a member of the immunoglobulin superfamily, that mediates homophilic and heterophilic cell-cell adhesion. CD31 is expressed on endothelial cells, platelets, and subsets of leucocytes. In the human and mouse, multiple alternatively spliced isoforms have been identified, and this alternative splicing may be involved in the regulation of ligand specificity. CD31-mediated endothelial cell-cell interactions are involved in angiogenesis in the mouse and rat. In addition, PECAM-1 has been demonstrated to play an important role in extravasation of leucocytes in vivo, but in vivo treatment with TLD-3A12 mAb had no discernable effect upon the inflammatory infiltrate in experimental allergic encephalomyelitis. The TLD-3A12 mAb partially blocks the proliferative response of antigen-specific CD4+ T cells to antigen-presenting cells and relevant antigen. This CD31 antibody crossreacts with pig endothelial cells and platelets, as determined by immunohistochemical staining of acetone-fixed frozen sections and immunofluorescent staining with flow cytometric analysis, respectively. A suspension of Lewis rat microglial cells was used as the the immunogen.

The antibody was conjugated to BD Horizon™ BV786 which is part of the BD Horizon Brilliant™ Violet family of dyes. This dye is a tandem fluorochrome of BD Horizon BV421 with an Ex Max of 405nm and an acceptor dye with an Em Max at 786nm. BD Horizon BV786 can be excited by the violet laser and detected in a filter used to detect Cy™7-like dyes (eg, 780/60nm filter). BV786 is a tandem fluorochrome of BD Horizon BV421 and an acceptor dye with an emission maximum at 786 nm. BV786 offers a bright choice for the 6th detector off the violet laser.
