Secreted phosphoprotein 1 (SPP1) is a multifunctional protein expressed by cells from a large variety of tissues. It is involved in many physiological and pathological processes, including bone metabolism, inflammation progress, tumor metastasis, injury repair, and hyperoxia-induced injury. Native SPP1 from multiple species have been isolated from the milk and urine, and recombinant SPP1 with different tags have been expressed and purified from bacteria. In our study, DNA fragments corresponding to mouse SPP1 without signal peptide were built into the pET28a(+) vector, and non-tagged recombinant mouse SPP1 (rmSPP1) was expressed in Escherichia coli BL21(DE3). rmSPP1 was purified using a novel tri-step procedure, and the product features high purity and low endotoxin level. rmSPP1 can effectively increase hepatocellular carcinoma cell (HCC) proliferation in vitro, demonstrating its biological activity.
