{"product_id":"cst-87318s","title":"CST,  87318S, Human SCF Recombinant Protein","description":"Growth Factors and Cytokines for studying SCF in the research area.\n\n\u003cb\u003eStorage\u003c\/b\u003e\nHuman SCF Recombinant Protein is supplied as lyophilized material that is very stable at -20°C. It is recommended to reconstitute with sterile water at a concentration of 0.1 mg\/ml which can be further diluted in aqueous solutions as needed. Addition of a carrier protein (0.1% HSA or BSA) is recommended for long-term storage. Once in solution, store at 4°C and use within 1 month, or store at -20ºC to -80ºC and use within 3 months to prevent loss of potency. Aliquot to avoid multiple freeze\/thaw cycles if storing reconstituted material at -20ºC to -80ºC.\n\u003cb\u003eSource \/ Purification\u003c\/b\u003e\nRecombinant human SCF was expressed in and is supplied in a lyophilized form.\n\u003cb\u003eBackground\u003c\/b\u003e\nStem cell factor (SCF) is produced by endothelial cells, fibroblasts, keratinocytes, gut epithelial cells, and tumor cells (1,2). SCF is critical for hematopoiesis and mast cell differentiation and has additional roles in survival and function of other cell types (1). Some tumor cell proliferation and invasiveness are promoted by SCF (3). Tumor-derived SCF appears to be involved in expansion of myeloid-derived suppressor cells that in turn limits proliferation of tumor-infiltrating T cells (4). SCF may have additional roles in the tumor microenvironment (2). SCF is either soluble or an integral membrane protein and the form is dependent on variation in splicing or proteolytic release (1). SCF binds to the receptor tyrosine kinase c-Kit and induces activation of the Akt, Erk, JNK, and p38 pathways (5,6).","brand":"CST","offers":[{"title":"Default Title","offer_id":46800717545641,"sku":"87318S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-87318s","provider":"Iright","version":"1.0","type":"link"}
