Detects human PDGF R beta in direct ELISAs and Western blots. In direct ELISAs, approximately 10% cross-reactivity with recombinant mouse PDGF R beta is observed, and less than 1% cross-reactivity with recombinant human PDGF sR alpha is observed.
Polyclonal Goat IgG
Mouse myeloma cell line NS0-derived recombinant human PDGF R beta Leu33-Phe530 (Glu241Asp) Accession # P09619
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied as a 0.2 µm filtered solution in PBS.
<0.10 EU per 1 μg of the antibody by the LAL method.
Recombinant Human PDGF R beta Fc Chimera (Catalog # 385-PR)
2.5 µg/106 cells
BUD‑8 human fibroblast cell line
Measured by its ability to neutralize PDGF R beta inhibition of PDGF-BB-dependent proliferation in the NR6R‑3T3 mouse fibroblast cell line. The Neutralization Dose (ND50) is typically 10-40 µg/mL in the presence of 2 μg/mL Recombinant Human PDGF R beta Fc Chimera and 4 ng/mL Recombinant Human PDGF-BB.
Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.
PDGF R beta was detected in immersion fixed paraffin-embedded sections of human breast cancer tissue using 15 µg/mL Goat Anti-Human PDGF R beta Antigen Affinity-purified Polyclonal Antibody (Catalog # AF385) overnight at 4 °C. Tissue was stained with the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue).

PDGF R beta Inhibition of PDGF-BB-dependent Cell Proliferation and Neutralization by Human PDGF R beta Antibody.
Recombinant Human PDGF R beta Fc Chimera (Catalog # 385-PR) inhibits Recombinant Human PDGF-BB (Catalog # 220‑BB) induced proliferation in the NR6R‑3T3 mouse fibroblast cell line in a dose-dependent manner (orange line). Inhibition of Recombinant Human PDGF-BB (4 ng/mL) activity elicited by Recombinant Human PDGF R beta Fc Chimera (2 μg/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Human PDGF R beta Antigen Affinity-purified Polyclonal Antibody (Catalog # AF385). The ND50 is typically 10‑40 µg/mL.

Background: PDGF R beta
PDGF is a major serum mitogen that can exist as a homo or hetero-dimeric 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. Where as PDGF R alpha binds all three PDGF isoforms with high affinity, PDGF R beta binds PDGF-BB only with high-affinity. 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 hetero-dimerization and signal transduction. The expression of the alpha and beta receptors is independently regulated in various cell types. Recombinant soluble PDGF R beta binds PDGF with high affinity and is potent PDGF antagonist.
