| Conjugation: | Unconjugated |
| Formulation: | Lyophilized from a solution in PBS pH 7.4, 5% Trehalose, 5% Mannitol. |
| Dilution Range: | Reconstitute in sterile water for a stock solution. |
| Storage Instruction: | Use a manual defrost freezer and avoid repeated freeze thaw cycles. Store at 2 to 8°C for one week. Store at-20 to-80°C for twelve months from the date of receipt. |
| Endotoxin: | <0.1 EU/Mu g of the protein by the LAL method. |
| Immunoreactivity: | Measured by the ability of the Immobilised protein to support the adhesion of human embryonic kidney cells (HEK293). Recombinant human OPN/Spp1 coated plate, cell adhesion is enhanced in a dose-dependent manner after 1 hour incubation at 37 °C. The E |
| Gene Symbol: | SPP1 |

| Uniprot ID: | OSTP_HUMAN |
| Immunogen Region: | Ile17-Asn300 |
| Immunogen: | Homo sapiens (Human) |
| 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. |
