PDGFR (Platelet-Derived Growth Factor Receptor) is a receptor tyrosine kinase for the PDGF family of growth factors. PDGF homo and hetero- dimmers (dimer of A (17kD) and B (14kD) chains (AA, AB, or BB)) bind to the two structurally related a and b PDGF Receptors (PDGFRa and PDGFRb). The type A PDGF Receptor binds all three PDGFs with high affinity, whereas the type B PDGF Receptor is selective for PDGF-BB. This binding results in the dimerization of the receptor and the subsequent kinase activation of the receptor tyrosine kinase (RTK) and its autophosphorylation. These phosphorylations allow for various proteins, such as PI3 Kinase, PLCg, and Grb2, to bind through their SH2 domains and transduce signals into the cell. The activation of PDGFFR triggers the intracellular loop and activates Ras, Erk1/2, and ROS. PDGFb has been implicated in embryonic development, angiogenesis, and development of tumors of glial origin. Applications: Suitable for use in FLISA, Western Blot and Immunohistochemistry. Other applications not tested. Recommended Dilution: Immunohistochemistry: Paraffin Optimal dilutions to be determined by the researcher. Storage and Stability: Store product at 4C in the dark. DO NOT FREEZE! Stable at 4C for 12 months after receipt as an undiluted liquid. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer.
