The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 1 µg/ml. Predicted molecular weight: 35 kDa. Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.
FunctionBinds tightly to hydroxyapatite. Appears to form an integral part of the mineralized matrix. Probably important to cell-matrix interaction. Acts as a cytokine involved in enhancing production of interferon-gamma and interleukin-12 and reducing production of interleukin-10 and is essential in the pathway that leads to type I immunity.
Tissue specificityBone. Found in plasma.
Sequence similaritiesBelongs to the osteopontin family.
Post-translational modificationsExtensively phosphorylated on clustered serine residues. N- and O-glycosylated. Phosphorylation sites are present in the extracelllular medium.
