From: Using anti-poly(ethylene glycol) bioparticles for the quantitation of PEGylated nanoparticles

Quantification of PEGylated nanomolecules by anti-PEG bioparticle-based sandwich ELISA.
Anti-PEG bioparticles acted as the capture reagents and AGP4-biotin as the detection antibody to measure the concentration of (A) PEG-QD (B) Lipodox, (C) PEG5K-SPIO and (D) PEGASYS. Representative data from three independent experiments are shown. Data represents mean ± SD.
