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).
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.
