Secreted Phosphoprotein 1 (SPP1) recombinant human protein is supplied as a lyophilized powder. This protein is suitable for use in analysis of protein structure. In general, recombinant proteins can also be used as an immunogen, as a protein standard, or in cell biology research applications.

This recombinant protein is expressed from a DNA sequence encoding the pro form of human SPP1 (NP_001035147.1) (Met 1-Asn 314)fused to a polyhistidine tag at the C-terminus.

N-terminal Sequence Analysis: IIe 17.

Activity: The activity of this protein has not been tested.

Formulation: lyophilized in PBS, pH 7.4, 5% mannitol, 5% trehalose, 0.02% Tween®-80.

Reconstitution: Dissolve the protein in sterile double-distilled water to a concentration of 0.2 mg/mL or lower. It is recommended that the protein be aliquoted and used as soon as possible. Store aliquots under sterile conditions at -20°C. Avoid repeated freeze-thaw cycles.

Expiration Date: expires one year from date of receipt when stored as instructed.

Secreted phosphoprotein 1, is a member of the osteopontinfamily. It is an extracellular structural protein and thereforean organic component of bone. Secreted phosphoprotein 1 is expressed in bone, although it is also expressed in other tissues. Secreted phosphoprotein 1 acts as acytokine which 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. Secreted phosphoprotein 1 has been implicated as an important factor in bone remodeling. Specifically, research suggests it plays a role in anchoring osteoclasts to the mineral matrix of bones. The fact that Secreted phosphoprotein 1 interacts with multiple cell surface receptors which are ubiquitously expressed makes it an active player in many physiological and pathological processes including wound healing, bone turnover, tumorigenesis, inflammation and ischemia. Therefore, manipulation of plasma Secreted phosphoprotein 1 levels may be useful in the treatment of autoimmune diseases, cancer metastasis, osteoporosis and some forms of stress.
