Western Blot; Detected samples: Hela whole cell lysate, Jurkat whole cell lysate, 293 whole cell lysate, HepG2 whole cell lysate; Untreated (-) or treated (+) with 30mM sodium butyrate for 4h; All lanes: HIST1H4A antibody at 1:2000; Secondary; Goat polyclonal to rabbit IgG at 1/40000 dilution; Predicted band size: 12 kDa; Observed band size: 12 kDa
Immunofluorescence staining of Hela cells (treated with 30mM sodium butyrate for 4h) with CAC11431 at 1:37.5, counter-stained with DAPI. The cells were fixed in 4% formaldehyde, permeabilized using 0.2% Triton X-100 and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4°C. The secondary antibody was Alexa Fluor 488-congugated AffiniPure Goat Anti-Rabbit IgG(H+L).
Immunocytochemistry analysis diluted at 1:75 and staining in Hela cells (treated with 30mM sodium butyrate for 4h) performed on a Leica BondTM system. The cells were fixed in 4% formaldehyde, permeabilized using 0.2% Triton X-100 and blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a biotinylated secondary antibody and visualized using an HRP conjugated SP system.
Chromatin Immunoprecipitation Hela (4*106, treated with 30mM sodium butyrate for 4h) were treated with Micrococcal Nuclease, sonicated, and immunoprecipitated with 5µg anti-HIST1H4A (CAC11431) or a control normal rabbit IgG. The resulting ChIP DNA was quantified using real-time PCR with primers against the ß-Globin promoter.
