Intracellular Flow Cytometry analysis of HepG2 (Human hepatocellular carcinoma epithelial cell) labeling FOXP1 with purified ab227649 at 1/20 dilution (12μg/ml) (red). Cells were fixed with 4% paraformaldehyde and permeabilised with 90% methanol. Goat anti rabbit IgG (Alexa Fluor^® 488, ab150077) at 1/2000 dilution was used as a secondary antibody. Isotype control -Rabbit monoclonal IgG (ab172730) / Black. Unlableled control -Unlabelled cells / blue. This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab227649).

ab227649 staining FOXP1 in A549 (positive) and A549-FOXP1 (negative) cells. The cells were fixed with 100% methanol (5 min), permeabilized with 0.1% PBS-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 for 2 hours at room temperature with ab227649 at 1ug/ml (shown in green) and ab7291, Anti-alpha Tubulin antibody [DM1A] - Loading Control (shown in pseudocolour magenta). Cells were then incubated with ab150081, Goat Anti-Rabbit IgG H&L (Alexa Fluor^® 488) preadsorbed at 1/1000 dilution and ab150119, Goat Anti-Mouse IgG H&L (Alexa Fluor^® 647) preadsorbed at 1/1000 dilution for 1 hour at room temperature.

This data was developed using ab227649, the same antibody clone in a different buffer formulation.

Blocking and diluting buffer and concentration : 5% NFDM/TBST.

Lysate was freshly made and used for Western blotting immediately to minimize protein degradation.

ab227649 is less sensitive than ab314488 in WB. We recommend using ab314488 for WB testing.
