MAB194P Monoclonal Antibody to Human Osteopontin, N-terminal

Background   Human Osteopontin (OPN) is a negatively charged, hydrophilic protein of 314 amino acids and is subject to significant post translational modifications (PTMs) including phosphorylation and glycosylation.  Due to its acidic nature and PTMs, OPN runs anomalously by SDS-PAGE.  Although its mass is 35kD, apparent molecular weights may range up to 75kD.  In addition, OPN is subject to proteolytic modification into smaller molecular weight fragments.
