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.
The antibody was conjugated to BD Horizon™ BV510 which is part of the BD Horizon Brilliant™ Violet family of dyes. With an Ex Max of 405-nm and Em Max at 510-nm, BD Horizon BV510 can be excited by the violet laser and detected in the BD Horizon V500 (525/50-nm) filter set. BD Horizon BV510 conjugates are useful for the detection of dim markers off the violet laser.
