Fig. 5From: Rational design of Raman-labeled nanoparticles for a dual-modality, light scattering immunoassay on a polystyrene substrateSDS-PAGE analysis of PEGylated antibodies. SDS-PAGE analysis confirmed successful antibody PEGylation. The gel was stained using Coomassie Blue to detect protein (blue/green on the gel) and a barium chloride iodine mixture to detect PEG (brown). The image contrast for Fig. 5 was uniformly adjusted to highlight each individual band in the gelBack to article page
