There are a number of ELISA Kits available for the measurement of CD322, another term for the human protein, junctional adhesion molecule 2. Other synonyms may include: junctional adhesion molecule B, JAM-IT/VE-JAM, vascular endothelial junction-associated molecule, C21orf43, JAM-B, JAMB, and PRO245. It is encoded by the JAM2 gene to yield a protein 298 amino acids in length and 33.2 kDa in size. However, there are up to 3 reported isoforms. The protein is categorized into the Immunoglobulin superfamily. Versions of CD322 are present in other organisms, including: Mouse, Rat, Frog.
