Flow Cytometry (Intracellular) - Alexa Fluor® 488 Anti-Fatty Acid Synthase antibody [EPR7465] (AB204660)

Flow cytometry overlay histogram showing left wild-type HAP1 positive cells and right negative FASN knockout HAP1 stained with ab204660 (red line). The cells were fixed with 4% formaldehyde (10 min) and then permeabilised with 0.1% PBS-Triton X-100 for 15 min. The cells were then incubated in 1x PBS containing 10% normal goat serum to block non-specific protein-protein interaction followed by the antibody (ab204660) (1x 10⁶ in 100μl at 5 μg/ml (1/100)) for 30min at 22°C.

Isotype control antibody was Alexa Fluor^® 488 Rabbit IgG, monoclonal [EPR25A] - Isotype Control (ab199091) (black line) used at the same concentration and conditions as the primary antibody. Unlabelled sample (blue line) was also used as a control.

Acquisition of >5000 events were collected using a 50 mW Blue laser (488nm) and 525/40 bandpass filter.

This antibody gave a positive signal in wild-type HAP1 fixed with 80% methanol (5 min) and then permeabilised with 0.1% PBS-Triton X-100 for 15 min under the same conditions.

This data was acquired using a Beckman Coulter CytoFlexLX flow cytometer.

ab204660 staining Fatty Acid Synthase in A549 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 ab204660 at 1/200 dilution (shown in green) and ab195889, Mouse monoclonal to alpha Tubulin (Alexa Fluor^® 594), at 1/250 dilution (shown in red). Nuclear DNA was labelled with DAPI (shown in blue).

Image was taken with a confocal microscope (Leica-Microsystems, TCS SP8).
