Anti-pas4 antibodies enable researchers to detect and measure the pas4 antigen in biological samples. This target is a reported synonym of the CD36 gene, which encodes CD36 molecule. This protein is known to function in the apoptotic pathway and cell adhesion, among other biological roles. The human version of pas4 has a canonical amino acid length of 472 residues and a protein mass of 53.1 kilodaltons, although 4 isoforms have been identified. It is reported to be localized in the Golgi and cell membrane of cells and notably expressed in many tissues, such as in adipose tissue and bone marrow. pas4 is a member of the CD36 protein family.
