ab203432 staining HP1α in wild-type HAP1 cells (top panel) and HP1α in wild-type HAP1 cells (bottom panel). The cells were fixed with 100% methanol (5min), permeabilized with 0.1% Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated with ab203432 at 1/500 dilution (shown in pseudo colour green) and ab7291 at 1μg/ml concentration overnight at +4°C, followed by a further incubation at room temperature for 1h with a goat secondary antibody to Mouse IgG (Alexa Fluor® 647) (ab150119) at 2 μg/ml (shown in red). Nuclear DNA was labelled in blue with DAPI.

This product also gave a positive signal under the same testing conditions in HAP1 cells fixed with 4% formaldehyde (10 min).

ab203432 staining HP1 in MCF7 cells. The cells were fixed with 4% formaldehyde (10 min), permeabilized with 0.1% Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated overnight at +4°C with ab203432 at a 1/50 dilution (shown in green) and ab195884, Rat monoclonal to alpha Tubulin (Alexa Fluor^® 647), at a 1/250 dilution (shown in red). Nuclear DNA was labelled with DAPI (shown in blue).
