应用 | Western Blot,Immunohistochemistry,Neutralization |
目标/特异性 | Detects human PDGF R alpha in direct ELISAs and Western blots. In direct ELISAs, less than 2% cross-reactivity with recombinant mouse PDGF R alpha, recombinant human (rh) PDGF R beta, rhFGF R2, and rhFGF R3 is observed. |
使用方法 | Western Blot: 0.1 µg/mL Immunohistochemistry: 5-15 µg/mL Neutralization: Measured by its ability to neutralize PDGF‑AA-induced proliferation in the WS-1 human fetal skin fibroblast cell line. The Neutralization Dose (ND50) is typically 1-6 µg/mL in the presence of 10 ng/mL Recombinant Human PDGF‑AA. |

背景 | 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 Flt-3 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). |

Cell Proliferation Induced by PDGF‑AA and Neutralization by Human PDGF R alpha Antibody. Recombinant Human PDGF‑AA (Catalog # 221-AA) stimulates proliferation in the WS-1 human fetal skin fibroblast cell line in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Human PDGF‑AA (10 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Human PDGF R alpha Antigen Affinity-purified Polyclonal Antibody (Catalog # AF‑307‑NA). The ND50 is typically 1-6 µg/mL. | |
