HepG2 cell; 4% Paraformaldehyde-fixed; Triton X-100 at room temperature for 20 min; Blocking buffer (normal goat serum, C-0005) at 37°C for 20 min; Antibody incubation with (Caspase-9) polyclonal Antibody, Unconjugated (bs-20773R) 1:100, 90 minutes at 37°C; followed by a conjugated Goat Anti-Rabbit IgG antibody at 37°C for 90 minutes, DAPI (blue, C02-04002) was used to stain the cell nuclei.

Overlay histogram showing Hela cells(1ug/1x10^6 cells) stained with bs-20773R (Green line). The cells were fixed with 80% methanol (5 min) and and then permeabilized with 0.01M PBS-Tween for 20 min . The cells were then incubated in 1x PBS/10% normal goat serum to block non-specific protein-protein interactions followed by the antibody for 30 min at 22℃. The secondary antibody used was fluorescein isothiocyanate goat anti-rabbit IgG (H+L) (bs-0295G-FITC , Brillant blue line) at 1/200 dilution for 30 min at 22℃. Isotype control antibody was rabbit IgG (polyclonal,bs-0295P,Orange line) used under the same conditions. Unlabelled sample (blue line) was also used as a control. Acquisition of 20,000 events were collected using a 20mW Argon ion laser (488nm) and 525/30 bandpass filter.
