Experimental details: Immunofluorescent analysis of Bax (green) showing staining in the cytoplasm of Hela cells (right) compared to a negative control without primary antibody (left). Formalin-fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 5-10 minutes and blocked with 3% BSA-PBS for 30 minutes at room temperature. Cells were probed with a Bax monoclonal antibody (Product # MA5-14003) in 3% BSA-PBS at a dilution of 1:50 and incubated overnight at 4 ºC in a humidified chamber. Cells were washed with PBST and incubated with a DyLight-conjugated secondary antibody in PBS at room temperature in the dark. F-actin (red) was stained with a fluorescent red phalloidin and nuclei (blue) were stained with Hoechst or DAPI. Images were taken at a magnification of 60x.

( C , F )--Intensity levels of BCL-2 ( C ) and BAX ( F ) were determined by confocal imaging. We analyzed individual cells that had fluorescence of secondary antibodies. The quantative data reflecting the level of BCL-2 or BAX expression are presented as fluorescence intensity values in summary bar charts (mean +- SEM). The values were averaged by 150 cells for each column. The results obtained after immunostaining agree with the data of fluorescence presented in panels ( A , B , D , E ). Each value is the mean +- SE ( n >= 3, p < 0.05). Statistical significance was assessed using paired t -test. Black asterisks represent comparison of baseline expression levels after incubation with different sized nanoparticles versus control. Red asterisks represent comparison of expression level after incubation with different-sized SeNPs versus OGD/R-induced levels; n/s--data not significant ( p > 0.05), * p < 0.05, ** p < 0.01, *** p < 0.001.
