Anti-Human PDGF-AA

Purified Recombinant Human PDGF-AA (>98%)

This antigen affinity purified polyclonal antibody has been 0.2 µm filtered and lyophilized from modified Dulbecco’s phosphate buffered saline (1X PBS) pH 7.2 – 7.3 containing 5.0% w/v trehalose with no calcium, magnesium, or preservatives present.

Lyophilized

The lyophilized antigen affinity purified polyclonal antibody can be stored desiccated at -20°C to -70°C for twelve months from date of receipt. The reconstituted antibody can be stored for at least four weeks at 2-8°C. For long-term storage of the reconstituted antibody, aseptically aliquot into working volumes and store at -20°C to -70°C in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles. No detectable loss of activity was observed after six months.

Immunohistochemistry: Suitable for use at concentration of 5-15 µg/mL.
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.

Rabbit Anti-Human Platelet Derived Growth Factor-AA (PDGF-AA ) recognizes Human PDGF-AA . This antigen affinity purified polyclonal antibody was purified using a proprietary chromatographic technique that includes covalently immobilizing the antigen proteins or peptides to agarose based beads. This purification method enhances specificity, reduces nonspecific binding of extraneous IgG and provides you with the most reliable reagent available for your early discovery research.

Platelet-derived growth factor (PDGF), an agent with important mitogenic effects for bone cells, exists in three isoforms, PDGF-AA, - BB, and –AB.¹ The A-chain homodimers of the platelet-derived growth factor (PDGF AA) are widely expressed in normal and transformed cells.² PDGF AA is a potent mitogen for a wide range of cell types including fibroblast, smooth muscle, and connective tissue. PDGF-AA and its receptor represent an important epithelial-mesenchymal interaction which plays a critical role in early lung branching morphogenesis.³ PDGF AA is also an essential autocrine regulator for vascular endothelial growth factor (VEGF) expression. It regulates the frequency and level of VEGF expression during the transition from a precancerous lesion to advanced cancer.⁴
