Anti-Periostin antibodies are available from several suppliers. In humans, this protein is encoded by the gene POSTN. The protein may also be known as Osteoblast Specific Factor 2, OSF-2, OSF2, PDLPOSTN, PN, and osteoblast specific factor 2 (fasciclin I-like). The expected protein mass is 93.3 kDa, but there are 7 reported isoforms. Variants of this antigen may also be found in other species, including canine, porcine, monkey, mouse and rat. Antibodies to the Periostin antigen may be useful for studying growth factor signaling.
