Recombinant human PDGFbb (Cat.NO. HZ-1308) stimulates proliferation of BALB/3T3 (mouse fibroblast cell line) in a dose dependent manner (blue curve, refer to bottom X-left Y axis). The activity of human PDGFbb (20ng/mL HZ-1308) is neutralized by mouse anti-human PDGFbb monoclonal antibody 69020-1-Ig at serial dose (red curve, refer to top X-right Y axis). The ND50 is typically 20-50 μg/mL.

The activity of human PDGF bb (20 ng/mL HZ-1308) is neutralized by mouse anti-human PDGF bb monoclonal antibody 69020-1-Ig at serial dose (red curve, refer to top X-right Y axis). The ND50 is typically 20-50 μg/mL. The NeutraControl mouse anti-human PDGF bb monoclonal antibody 69520-1-Ig could recognize human PDGF bb, but could not neutralize human PDGF bb at the range of 3.125-200 μg/mL(green curve, refer to top X-right Y axis).
Indirect ELISA was carried out by coating recombinant Human PDGF bb (Cat.NO. HZ-1308) at 70 ng/well followed by blocking and adding serial diluted PDGF bb antibody 69020-1-Ig and 69520-1-Ig respectively. Signal was developed with TMB and stopped by H2SO4. Signal strength was measured by absorbance at 450 nm.
