Goat anti Human Osteopontin antibody recognises an epitope within the C-terminal (CT) region of osteopontin, an acid-rich, multidomain, phosphorylated ~60 kDa glycoprotein. Osteopontin is a secreted chemokine-like protein and member of the SIBLING family, and is synthesised by many cell types.Osteopontin is involved in enhancing production of interferon-gamma and interleukin-12 and reducing production of interleukin-10. It is essential in the pathway that leads to type I immunity. Osteoponitn is also thought to be important to cell-matrix interaction, and can bind fibronectin, collagen and calcium.Osteopontin has been suggested to have a role in atherosclerosis, bone remodelling, angiogenesis, wound healing and tissue injuries.
