The 401901 monoclonal antibody specifically recognizes Junctional adhesion molecule-like (JAML) which is also known as Adhesion molecule interacting with CXADR antigen 1 (AMICA), or Dendritic cell-specific protein CREA7-1. JAML (AMICA) is a ~65 kDa single-pass type I transmembrane glycoprotein that is encoded by JAML which belongs to the junctional adhesion molecule (JAM) family within the Ig gene superfamily. The extracellular region of this adhesion molecule contains two Ig domains followed by a transmembrane segment and a cytoplasmic domain involved in activation signaling. JAML (AMICA) is expressed on some leucocytes including granulocytes, monocytes, γδ T cells and effector memory αβ T cells. Leucocyte JAML (AMICA) forms a homodimer that can interact with CXADR (Coxsackie virus and adenovirus receptor, also known as CAR), a cell-surface membrane receptor found in the tight junctional complexes of adjacent endothelial or epithelial cells. These heterophilic interactions can function in leucocyte activation and the regulation of leucocyte migration through epithelial and endothelial tissues, eg, during inflammatory responses or wound healing.
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.
