Measured in a cell proliferation assay using Balb/3T3 mouse embryonic fibroblast cells.The ED50 for this effect is less than 300 ng/ml.
＞90% as determined by reducing SDS-PAGE.
Stability and Storage
Lyophilized protein should be stored at < -20℃, though stable at room temperature for 3 weeks.Reconstituted protein solution can be stored at 4-7℃ for 2-7 days.Aliquots of reconstituted samples are stable at < -20℃ for 3 months
AP Mol Mass
Lyophilized from a 0.2 μm filtered solution of 4mM HCl.
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.
Aplha, transcription related growth factors and stimulating factors or repressing nuclear factors are complex subunits of proteins involved in cell differentiation. Complex subunit associated factors are involved in hybridoma growth, Eosinohils, eritroid proliferation and derived from promotor binding stimulating subunits on the DNA binding complex. NFKB 105 subunit for example is a polypetide gene enhancer of genes in B cells.Platelets, also called thrombocytes or cloth cells in blood and are needed to stop bleeding by clumping and clotting the blood the vessels when the an injury occurs. Teh bone marrow will produce the platelets that have no nucleus. Platelates are unique to mammals, the are curved shaped 1900nm to 3100 nm large nucleus free clothing structures.
Human proteins, cDNA and human recombinants are used in human reactive ELISA kits and to produce anti-human mono and polyclonal antibodies. Modern humans (Homo sapiens, primarily ssp. Homo sapiens sapiens). Depending on the epitopes used human ELISA kits can be cross reactive to many other species. Mainly analyzed are human serum, plasma, urine, saliva, human cell culture supernatants and biological samples.
