Figure 6From: Chemistry of conjugation to gold nanoparticles affects G-protein activity differentlySchematic illustration of consequence of AuNP conjugation on Gαi1 function. Group (A) displays fold change by covalent conjugate for binding of AlF4- (A-1), uptake of GTPγS (A-2), GTP hydrolysis (A-3) (B) corresponds to unconjugated Gαi1. Group (C) displays fold change by non-covalent conjugate for binding of AlF4- (C-1), uptake of GTPγS (C-2), GTP hydrolysis (C-3).Back to article page
