Purified (~70-90%). PDGFRa (platelet-derived growth factor receptor A) is a member of the PDGFR family of membrane receptors with intrinsic tyrosine kinase activity. Aberrant expression of PDGFRa has been linked to developmental abnormalities in vertebrate models and has been implicated in multiple disease states in humans. There is widespread expression of PDGFRa in renal cell types involved in fibrotic and sclerosing processes. PDGF and its receptor PDGFRa are inducers of fibrosis in the repair phase of inflammatory bowel disease and they may also be involved in the active inflammatory phase. Source: Recombinant protein corresponding to mouse PDGFR alpha fused to GST-Tag at N-terminal expressed in Insect cells. Molecular Weight: ~100kD Specific Activity: 14nmol/min/mg as per activity assay protocol.
