产品描述 概述Recombinant Human Platelet-derived Growth Factor AA is produced by our E.coli expression system and the target gene encoding Ser87-Thr211 is expressed with a 6His tag at the N-terminus. 使用说明This material is offered by Novin Biotech for research, laboratory or further evaluation purposes. NOT FOR HUMAN USE. 技术规格Tag | N-6His | 种属 | Human | 表达系统 | E.coli | Accession# | P04085 | Source | E.coli | Formulation_Description | Lyophilized from a 0.2 μm filtered solution of 4mM HCl. | Storage | Lyophilized protein should be stored at < -20°C, thoμgh stable at room temperature for 3 weeks.Reconstituted protein solution can be stored at 4-7°C for 2-7 days.Aliquots of reconstituted samples are stable at < -20°C for 3 months. | Reconstitution | Dissolve the lyophilized protein in 4mM HCl . | Purity | Greater than 95% as determined by reducing SDS-PAGE. | Endotoxin | Less than 0.1 ng/μg (1 EU/μg) as determined by LAL test. | Background | Platelet-derived growth factor subunit A (PDGFA), belongs to the PDGF/VEGF growth factor family. PDGFA is a secreted protein, stored in platelet alpha-granules and released by platelets upon wounding. PDGFA is potent mitogens for a variety of cell types including smooth muscle cells, connective tissue cells, bone and cartilage cells, and some blood cells. It plays an essential role in the regulation of embryonic development, cell proliferation, cell migration, survival and chemotaxis. PDGFA is required for normal lung alveolar septum formation during embryogenesis, normal development of the gastrointestinal tract, normal development of Leydig cells and spermatogenesis, normal oligodendrocyte development and normal myelination in the spinal cord and cerebellum. It plays an important role in wound healing; Signaling is modulated by the formation of heterodimers with PDGFB. | Biological_Activity | Measured in a cell proliferation assay using Balb/3T3 mouse embryonic fibroblast cells. The ED50 for this effect is 20-160 ng/ml. |
