Western blot analysis of Phospho-FOXO1A (T24)+ FOXO3A (T32)+ FOXO4 (T28)+ FOXO6 (T26) on different lysates with Rabbit anti-Phospho-FOXO1A (T24)+ FOXO3A (T32)+ FOXO4 (T28)+ FOXO6 (T26) antibody at 1/1,000 dilution.
Lane 1: Jurkat cell lysate,
Lane 2: Jurkat treated with 20μM LY294002 for 2 hours cell lysate,
Lane 3: Jurkat treated with 100nM Calyculin A for 40 minutes cell lysate,
Lane 4: NIH/3T3 starved for 24 hours cell lysate,
Lane 5: NIH/3T3 starved for 24 hours then add 100nM Calyculin A for 30 minutes cell lysate,
Lysates/proteins at 20 µg/Lane.
Observed band size: 55-150 kDa
Exposure time: 20 seconds;
4-20% SDS-PAGE gel.
Proteins were transferred to a PVDF membrane and blocked with 5% NFDM/TBST for 1 hour at room temperature. The primary antibody at 1/1,000 dilution was used in 5% NFDM/TBST at 4℃ overnight. Goat Anti-Rabbit IgG - HRP Secondary Antibody at 1/50,000 dilution was used for 1 hour at room temperature.

Immunocytochemistry analysis of Jurkat cells treated with 20μM LY294002 for 2 hours (upper, negative) and Jurkat cells treated with 100nM Calyculin A for 40 minutes (lower, positive) labeling Phospho-FOXO1A (T24)+ FOXO3A (T32)+ FOXO4 (T28)+ FOXO6 (T26) with Rabbit anti-Phospho-FOXO1A (T24)+ FOXO3A (T32)+ FOXO4 (T28)+ FOXO6 (T26) antibody at 1/1,000 dilution.
Cells were fixed in 4% paraformaldehyde for 20 minutes at room temperature, permeabilized with 0.1% Triton X-100 in PBS for 5 minutes at room temperature, then blocked with 1% BSA in 10% negative goat serum for 1 hour at room temperature. Cells were then incubated with Rabbit anti-Phospho-FOXO1A (T24)+ FOXO3A (T32)+ FOXO4 (T28)+ FOXO6 (T26) antibody at 1/1,000 dilution in 1% BSA in PBST overnight at 4 ℃. Goat Anti-Rabbit IgG H&L (iFluor™ 488) was used as the secondary antibody at 1/1,000 dilution. PBS instead of the primary antibody was used as the secondary antibody only control. Nuclear DNA was labelled in blue with DAPI. Beta tubulin (red) was stained at 1/100 dilution overnight at +4℃. Goat Anti-Mouse IgG H&L (iFluor™ 594) was used as the secondary antibody at 1/1,000 dilution.

Flow cytometric analysis of Jurkat cells treated with 20μM LY294002 for 2 hours (left, negative) and Jurkat cells treated with 100nM Calyculin A for 40 minutes (right, positive) labeling Phospho-FOXO1A (T24)+ FOXO3A (T32)+ FOXO4 (T28)+ FOXO6 (T26).
Cells were fixed and permeabilized. Then stained with the primary antibody (1/1,000) (red) compared with Rabbit IgG Isotype Control (green). After incubation of the primary antibody at +4℃ for an hour, the cells were stained with a iFluor™ 488 conjugate-Goat anti-Rabbit IgG Secondary antibody at 1/1,000 dilution for 30 minutes at +4℃. Unlabelled sample was used as a control (cells without incubation with primary antibody; black).
