The H202-106 monoclonal antibody specifically binds to CD321 which is also known as JAM-1 (Junctional adhesion molecule 1), Junctional adhesion molecule A (JAM-A), and F11 Receptor (F11R). CD321 is a type I transmembrane glycoprotein that includes two extracellular immunoglobulin-like domains. CD321 functions as an adhesion receptor molecule on platelets. It also supports the tight junction formation between endothelial cells, where it may regulate the transendothelial migration of leucocytes, and some epithelial cells. CD321 expression by certain subsets of tissue-derived, MHC Class II-positive thymic epithelial cells, macrophages, and dendritic cells suggest that it may play a role in the organization and function of antigen presenting cells.
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.
