The CK41 monoclonal antibody specifically binds to Nectin-1, which is also known as, CD111, Poliovirus receptor-related protein 1(PRR1, PVRL1), Herpes virus entry mediator C (HveC), or Herpesvirus Ig-like receptor (HIgR). Nectin-1 is a type I transmembrane glycoprotein that belongs to the Ig gene superfamily. CD111 is expressed on a variety of cell types including, epithelial cells, endothelial cells, neuronal cells, megakaryocytes, and CD34 positive stem cells. CD111 functions as a receptor for herpes simplex virus 1 (HSV 1) and HSV 2. Nectin-1 also serves as an intercellular adhesion molecule helping to form junctions between cells, eg, between endothelial cells or epithelial cells. Nectin-1 can bind to other Nectin-1 molecules and Nectin family members and to CD155 (Poliovirus Receptor/PVR).
The antibody was conjugated to BD Horizon BUV615 which is part of the BD Horizon Brilliant™ Ultraviolet family of dyes. This dye is a tandem fluorochrome with an Ex Max near 350 nm and an Em Max near 615 nm. BD Horizon Brilliant BUV615 can be excited by the ultraviolet laser (355 nm) and detected with a 610/20 filter and a 595 nm LP. Due to the excitation of the acceptor dye by the blue/yellow-green laser line, there may be significant spillover into channels detecting PE-CF594 like emissions (eg, 610/20-nm filter).
