Figure Lengend Snippet: (A) Detection of detergent-soluble and - insoluble c-MYC proteins by immunoblotting in HeLa cells pre-treated with 30 μM CR, followed by HS at 43°C for 30 min (representative images of three independent experiments). (B) and (C) Immunoprecipitation of either exogenously expressed HA-c-MYC or endogenous c-MYC proteins in HeLa cells by A11 antibodies (representative images of three independent experiments). (D) Detection of endogenous c-MYC proteins in HeLa cells by PLA using both the goat anti-c-MYC Ab and the rabbit anti-AO (A11) Ab. Nuclei are counterstained with Hoechst 33342. Scale bar: 10 μm. (E)-(G) Detection of endogenous c-MYC proteins in human prostate adenocarcinoma, hepatocellular carcinoma, and Alzheimer’s disease brain tissues by brightfield PLA using both the goat anti-c-MYC Ab and the rabbit anti-AO (A11) Ab. Scale bar: 100 μm for low magnification and 10 μm for high magnification. (H): Quantitation of endogenous c-MYC recognized by both the goat anti-c-MYC Ab and the rabbit anti-AO (A11) Ab through In-Cell PLA ELISA in HeLa cells treated with CR (mean ± SD, n=3 independent experiments, One-way ANOVA).
