Anti-PAR1 antibodies are available from several suppliers. PAR1 is an alias name for the human gene F2R, also known as coagulation factor II thrombin receptor and protease-activated receptor 1. PAR1 is a 425-amino acid G-protein coupled receptor that is highly expressed in platelets and endothelial cells. Cleavage by thrombin activates PAR1.
