Article Title: A comparative analysis of EGFR-targeting antibodies for gold nanoparticle CT imaging of lung cancer

Figure Lengend Snippet: (A) shows the ELISA signal (reflecting EGFR binding) normalized by nanoparticle concentration. Both C225 and VHH-122 have high binding, while PEG has almost none. Differences in binding between all three nanoparticle types are statistically significant. (B) shows the ELISA signal normalized by antibody concentration. Here, C225 has much higher signal than VHH-122, consistent with its higher binding affinity and lower number of antibodies per nanoparticle.
Article Snippet: Antibody-conjugated AuNPs were blocked with 10% donkey serum in PBS, then incubated with a soluble recombinant human EGFR extracellular domain-Fc chimera (Sino Biological) at 10 nM in blocking buffer for 2 hours.
