Osteopontin Human Recombinant, HEK ( SPP1 Human, HEK )
DescriptionOsteopontin Human Recombinant is a single, glycosylated, polypeptide chain produced in HEK293 cells, is a full length protein (amino acids 17-314) fused with a polyhistidine tag at the C-terminus, having a total calculated molecular mass
Data sheet
| Formulation | Osteopontin was lyophilized from a 0.2uM filtered solution of 20mM PB and 150mM NaCl, pH 7.2. |
| Solubility | It is recommended to reconstitute the lyophilized SPP1 in 1xPBS to a concentration no less than 100 ug/ml, which can then be further diluted to other aqueous solutions. |
| Purity | Greater than 95.0% as determined by SDS-PAGE. |
| Description | Osteopontin Human Recombinant is a single, glycosylated, polypeptide chain produced in HEK293 cells, is a full length protein (amino acids 17-314) fused with a polyhistidine tag at the C-terminus, having a total calculated molecular mass of 34.5kDa (The actual molecular mass may be approximately 60-65kDa in SDS-PAGE under reducing conditions due to glycosylation).Osteopontin is purified by proprietary chromatographic techniques. |
| Protein Background | Osteopontin is a glycoprotein that was first identified in osteoblasts and is involved in bone remodeling, immune functions in fibroblasts, macrophages, and lymphocytes during inflammation and wound healing. SPP1 binds tightly to hydroxyapatite. SPP1 forms an integral part of the mineralized matrix. SPP1 is vital to cell-matrix interaction. Secreted Phosphoprotein-1 protects against cardiac ischemia-reperfusion injury via late preconditioning. Expression of both Ostepontin and CD44 in hepatocellular carcinoma is linked with advanced tumor stage and contributes to prognosis information. SPP1 is the most over-expressed gene in intrahepatic cholangiocarcinoma. Secreted Phosphoprotein-1 overexpression is related with interstitial lung diseases. |
| Expression host | HEK293 cells. |
