Fig. 4From: Enhanced sensitivity of VEGF detection using catalase-mediated chemiluminescence immunoassay based on CdTe QD/H2O2 systemSpecificity of the proposed CL-ELISA assay for VEGF detection over other interfering substance. Each independent experiment was repeated three times. VEGF, PDGF, TGFβ, HAS, BMP, IL-12, IL-2, IL-1β, IFNγ, IGF-1, and IgG4 samples were all prepared in a concentration of 50,000 pg mL−1. A negative control test was performed by adding PBSBack to article page
