Apoptosis antibody array. Cell lysates (300 μg) were incubated overnight with Abcam's human apoptosis antibody array-membrane. The antibody array membranes were then washed, and a cocktail of biotinylated antibody mix was used to detect apoptosis-related proteins. After incubation with HRP-conjugated streptavidin, the signal was visualised after 1- min exposure by chemiluminescence. Comparison of signal intensity was used to determine relative differences in expression levels of the proteins. Positive control spots were used for normalisation. Ag 1 is for 1 μg/mL AgNPs, Ag 10 is for 10 μg/mL.
