Western blot analysis of Histone H3.3 (phospho S31) on Hela cell lysates.
Lane 1: Hela cells, whole cell lysate, 10ug/lane
Lane 2/3: Hela cells treated with 100ng/ml Nocodazole for 18h, whole cell lysates, 10ug/lane
Lane 4: Hela cells treated with 100ng/ml Nocodazole for 18h, then treated with 2.8ug/ul lambda-PP for 30 minutes, whole cell lysates, 10ug/lane
All lanes :
Anti-Histone H3.3 (phospho S31) antibody at 1:500 dilution. Anti-GAPDH antibody at 1:10,000 dilution. Goat Anti-Rabbit IgG H&L (HRP) at 1/200,000 dilution.
Blocking and diluting buffer: 5% BSA.
Exposure time: 2 minutes 34 seconds
Proteins were transferred to a PVDF membrane and blocked with 5% NFDM/TBST for 1 hour at room temperature. The primary antibody at 1/500 dilution was used in 5% NFDM/TBST at room temperature for 2 hours. Goat Anti-Rabbit IgG - HRP Secondary Antibody at 1:200,000 dilution was used for 1 hour at room temperature.
WB
Western blot analysis of Phospho-Histone H3.3 (S31) on different lysates with Rabbit anti-Phospho-Histone H3.3 (S31) antibody at 1/1,000 dilution.
Exposure time: 1 minute;
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.
ICC/IF
Immunocytochemistry analysis of HeLa cells treated with or without 100ng/mL Nocodazole for 18 hours labeling Phospho-Histone H3.3 (S31) with Rabbit anti-Phospho-Histone H3.3 (S31) antibody at 1/25,000 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-Histone H3.3 (S31) antibody at 1/25,000 dilution in 1% BSA in PBST overnight at 4 ℃. Goat Anti-Rabbit IgG H&L (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 (594) was used as the secondary antibody at 1/1,000 dilution.
