Mouse anti Human CD321 antibody, clone F11 recognises human Junctional adhesion molecule A, also known as CD321, JAM-1, JAM-A, Platelet F11 receptor, Platelet adhesion molecule 1 or PAM-1. CD321 is a 272 amino acid ~35 kDa single pass type 1 transmembrane glycoprotein expressed by endothelium, epithlial tissues and some leukocytes (Ostermann et al. 2002). CD321 was originally identified as the F11 receptor expressed on platelets (Kornecki et al. 1990).

Mouse anti Human CD321 antibody, clone F11 is able to activate platelets, leading to aggregation and granule secretion (Kornecki et al. 1990, Naik et al. 1995).
