Scientific Data Images for Human PDGF R alpha Antibody

Cell Proliferation Induced by PDGF‑AA and Neutralization by Human PDGF R alpha Antibody.

Neutralization by Human PDGF R alpha Antibody

In a functional ELISA, Human PDGF R alpha Antibody (Catalog # MAB322) blocks the binding of Recombinant Human PDGF R alpha Fc Chimera Protein (6765-PR) to Recombinant Human PDGF AA (221-AA). The Neutralization Dose (ND50) for this effect is typically 40.0-400 ng/mL.

PDGF Ra antibody in Human Breast Cancer Tissue by Immunohistochemistry (IHC-P).

PDGF R alpha in Human Breast Cancer Tissue.

PDGF Ra was detected in immersion fixed paraffin-embedded sections of human breast cancer tissue using Mouse Anti-Human PDGF Ra Monoclonal Antibody (Catalog # MAB322) at 25 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue). Specific staining was localized to epithelial cells.

Background: PDGF R alpha

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).
