Opis

Opis ogólny

M.W. 65,000 and 30,000 under reducing conditions.

Recombinant, mouse osteopontin fused at the C-terminus to a His•Tag sequence and expressed in NSO-derived Leu¹⁷-Asn²⁹⁴ (Glu99Gly) murine myeloma cells. A secreted, highly acidic, Ca²⁺-binding, RGD-containing, phosphorylated glycoprotein. Chemotactic for macrophages, smooth muscle cells, endothelial cells, and glial cells. Has been shown to inhibit nitric oxide production and cytotoxicity by activated macrophages. Plays a significant role in inducing granulomas of various origin. OPN is also involved in the migration of embryonic fibroblasts, macrophages, and metastatic cells.

Recombinant, mouse osteopontin fused at the C-terminus to a His•Tag sequence and expressed in NSO-derived Leu¹⁷-Asn²⁹⁴ (Glu99Gly) murine myeloma cells. A secreted, highly acidic, calcium-binding, RGD-containing, phosphorylated glycoprotein. Osteopontin is expressed in several cell types including macrophages, fibroblasts, epithelial cells, T cells and osteoclasts in response to activation by cytokines, growth factors or inflammatory mediators. Mouse OPN cDNA encodes a 294 amino acid protein that has a 16 amino acid predicted signal peptide, which is cleaved to generate 278 amino acid mature protein. The mature protein contains an integrin binding arginine-glycine-aspartic acid (RGD) sequence. Exhibits some renoprotective actions in renal injury, such as increasing tolerance to acute ischemia, inhibiting inducible nitric oxide synthase, and reducing cell peroxide levels.

Działania biochem./fizjol.

~200 ng immobilized osteopontin/well will mediate the adhesion of ≥25% of the 293 cells plated at 10⁵ cells/well
