{"product_id":"cst-42028s","title":"CST,  42028S, Human PDGF-AA Recombinant Protein","description":"Growth Factors and Cytokines for studying PDGF-AA in the research area.\n\n\u003cb\u003eStorage\u003c\/b\u003e\nHuman PDGF-AA 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 PDGF-AA was expressed in and is supplied in a lyophilized form.\n\u003cb\u003eBackground\u003c\/b\u003e\nPDGF-AA is integrally involved in embryonic development, angiogenesis, and organogenesis and induces fibroblast proliferation and migration (1,2). PDGF-AA is produced by epithelial, muscle, osteosarcoma, and neuronal progenitor cells (1,3). Active PDGF-AA is formed through intracellular proteolytic cleavage of a large precursor. PDGF-AA is also concentrated in the extracellular matrix through alternative splicing that generates an extended carboxy-terminal that binds extracellular matrix components. The carboxy-terminal stretch is removed extracellularly to generate mature PDGF-AA (1,2). PDGF-AA binding to PDGFR-α activates the receptor tyrosine kinase (1). PDGF-AA-induced signaling is through the Ras-MAPK, PI3K\/Akt, and PLCγ pathways (1). Dysregulation of PDGF-AA expression and\/or signaling is often associated with cancer and fibrotic disorders (1).","brand":"CST","offers":[{"title":"Default Title","offer_id":46800713580713,"sku":"42028S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-42028s","provider":"Iright","version":"1.0","type":"link"}
