PDGFR alpha Antibody (PRa292) [Phycoerythrin] Summary

• Immunogen: Human osteosarcoma cell membrane extracts
• Specificity: Detects human PDGF R alpha . Recognizes the PDGF receptor alpha -subunit; it does not recognize the PDGF receptor beta -subunit. Binds to the PDGF receptor alpha -subunit of primate species (human, monkey, baboon) and dog. Does not recognize rat or mouse receptors and its ability to bind to receptors from other species has not been tested.

Background

PDGF is a major serum mitogen that can exist as a homo- or heterodimeric protein consisting of disulfide-linked PDGF-A and PDGF-B chains. The PDGF-AA, PDGF‑BB and PDGF-AB isoforms have been shown to bind to two distinct cell surface PDGF receptors with different affinities. Whereas PDGF R alpha binds all three PDGF isoforms with high affinity, PDGF R beta binds PDGF‑BB and AB, but not PDGF-AA. Both PDGF R alpha and PDGF R beta are members of the class III subfamily of receptor tyrosine kinases (RTK) that also includes the receptors for M-CSF, SCF and Flt3 ligand. All class III RTKs are characterized by the presence of five immunoglobulin-like domains in their extracellular region and a split kinase domain in their intracellular region. PDGF binding induces receptor homo-and heterodimerization and signal transduction. The expression of the alpha and beta receptors is independently regulated in various cell types. Only PDGF R alpha is expressed in oligodendrocyte progenitor cells, mesothelial cell and liver endothelial cells. Soluble PDGF-R alpha has been detected in cell conditioned medium and human plasma. Recombinant soluble PDGF R alpha binds PDGF with high affinity and is a potent PDGF antagonist (1).
