| Applications | SDS-PAGE/Bioactivity |
| Host | E.coli |
| Note | STRICTLY FOR FURTHER SCIENTIFIC RESEARCH USE ONLY (RUO). MUST NOT TO BE USED IN DIAGNOSTIC OR THERAPEUTIC APPLICATIONS. |
Product Properties
| Concentration | 1 mg/mL |
| Formulation | Liquid in 20mM Tris-HCl buffer (pH 7.5) containing 1mM DTT, 10% Glycerol, 2mM EDTA |
| Storage Instruction | For short term storage, keep at +2C to +8C for up to 1 week. For long term storage, aliquot and store at-20C, and avoid repeat freeze-thaw cycles. |
| Endotoxin | < 1 EU per 1ug of protein (determined by LAL method) |
| Immunoreactivity | Measured by the ability of the immobilized protein to support the adhesion of HEK293 human embryonic kidney cells. When cells are added to OPN coated plates 10ug/ml. This effect is more to 40%. |

Additional Info
| Tissue Specificity | Detected in cerebrospinal fluid and urine (at protein level). Bone. Found in plasma. |
| Post Translational Modifications | Forms covalent cross-links mediated by transglutaminase TGM2, between a glutamine and the epsilon-amino group of a lysine residue, forming homopolymers and heteropolymers, increasing its collagen binding properties. Extensively phosphorylated by FAM20C in the extracellular medium at multiple sites within the S-x-E/pS motif. The phosphorylated form inhibits hydroxyapatite crystallization. Dephosphorylation via a mechanism involving ALPL/TNAP promotes hydroxyapatite crystallization. O-glycosylated. Isoform 5 is GalNAc O-glycosylated at Thr-59 or Ser-62. |
| Function | Major non-collagenous bone protein that binds 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. |
