BD Pharmingen™ Purified Mouse anti-PDGFRβ (CD140b) (pY771)
Clone J23-618 (RUO)






Weste rn blot analysis of PDGFRβ (pY77 1). Lysates from control (left panel) and PDGF-treated (right panel) NIH/3T3 mouse embryonic fibroblasts were probed with purified mouse anti-PDGFRβ (CD140b) (pY 771) at concentrations of 0.016 (lanes 1 and 4) , 0.008 (lanes 2 and 5), and 0.004 µg/ml (lanes 3 and 6 ). PDGFRβ (pY 771) is identified as a band of 180 kDa in the treated cells.

PDGFRβ (pY 771) staining on tonsil. Fresh human tonsil was incubated in 5 mM Pervanadate solution for 2 hours, then fixed in formalin and processed. Following antigen retrieval with BD Retrievagen A buffer (Cat. no. 550524), the sections were either left untreated (left panel) or treated with a phosphatase to eliminate all phosphorylation (right panel). The tissue sections were stained with puri fied Mouse anti-PDGFRβ (CD140b) (pY 771) with Hematoxylin counterstaining. Original magnification: 20X.

Platelet-derived growth factor (PDGF) is a potent mitogen for cells of mesenchy mal origin and exerts its effects by binding to the PDGF receptor (PDGFR), a transmembrane protein tyrosine kinase. PDGFR is composed of PDGFRα (CD140a) and/or PDGFRβ (CD140b) polypeptides. Both PDGF and PDGFR consist of subunits that form homo- or heterodimers with varying specificities: PDGF-AA binds only to αα PDGFR, PDGF-AB binds to both αα and αβ PDGFR, and PDGF-BB binds to all three PDGFRs. Ligand binding indu ces dimerization and activation of the receptor. Upon activation, CD140b is phosphorylated at multiple tyrosine sites and, in turn, an intracellular phosphorylation cascade is initiated. PDGFR localizes primarily to membrane invaginations termed caveolae , compartments that are enriched in several of its downstream effectors, including phosphatidylinositol 3'-kinase, Src, and phospholipase C-γ.
The J23-618 monoclonal antibody recognizes the phosphorylated tyrosine 771 (pY771) in the kinase insert domain of CD140b . pY771 interacts with GTPase-activating protein, a negative regulator of Ras, and weakly with Shc, which indirectly promotes the activation of Ras .
