Neutralization
Measured by its ability to neutralize PDGF‑AA-induced proliferation in the NR6R‑3T3 mouse fibroblast cell line. Raines, E.W. et al. (1985) Methods Enzymol. 109:749. The Neutralization Dose (ND50) is typically 0.1-0.3 µg/mL in the presence of 25 ng/mL Recombinant Human PDGF‑AA.

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.

Data Examples

Neutralization Cell Proliferation Induced by PDGF‑AA and Neutralization by Human PDGF‑AA Antibody. View Larger

Cell Proliferation Induced by PDGF‑AA and Neutralization by Human PDGF‑AA Antibody. Recombinant Human PDGF-AA (Catalog # 221-AA) stimulates proliferation in the NR6R-3T3 mouse fibroblast cell line in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Human PDGF-AA (25 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Human PDGF-AA Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-221-NA). The ND50is typically 0.1-0.3 µg/mL.

Immunohistochemistry PDGF‑AA in Human Breast and Breast Cancer Tissue. View Larger

PDGF‑AA in Human Breast and Breast Cancer Tissue. PDGF-AA was detected in immersion fixed paraffin-embedded sections of human breast and breast cancer tissue using Goat Anti-Human PDGF-AA Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-221-NA) at 5 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Specific staining was localized to epithelial cells.

Background: PDGF-AA

Platelet-derived growth factor (PDGF) was discovered as a major mitogenic factor present in serum but absent from plasma. It was found to be secreted from the
alpha -granules of platelets activated during the coagulation of blood to form serum. Subsequent studies have demonstrated that PDGF is not one molecule but three, each a dimeric combination of two distinct but structurally related peptide chains designated A and B. The dimeric isoforms PDGF-AA, AB and BB are differentially expressed in various cell types and their effects are mediated through two distinct receptors, termed alpha and beta. Differences exist in isoform binding to each receptor. In general, PDGF isoforms are potent mitogens for connective tissue cells, including dermal fibroblasts, glial cells, arterial smooth muscle cells and some epithelial and endothelial cells. In addition to its activity as a mitogen, PDGF is chemotactic for fibroblasts, smooth muscle cells, neutrophils and mononuclear cells. Other reported activities for PDGF include stimulation of granule release by neutrophils and monocytes, facilitation of steroid synthesis by Leydig cells, stimulation of neutrophil phagocytosis, inhibition of natural killer (NK) cell activity, stimulation of collagen synthesis, modulation of thrombospondin expression and secretion, stimulation of collagenase activity and secretion, induction of contraction of rat aorta strips in vitro, and transient induction of T cell IL-2 secretion accompanied by a down-regulation of IL-4 and IFN-gamma production, temporary effects that may allow clonal expansion of antigen-activated B and T helper lymphocytes prior to differentiation. PDGF also appears to be ubiquitous in neurons throughout the CNS, where it is suggested to play an important role in neuron survival and regeneration, and in mediation of glial cell proliferation and differentiation.
