Immunocytochemistry/ Immunofluorescence - Anti-Chk1 (phospho S345) antibody [EPR30270-566] - BSA and Azide free (AB325676)

This data was developed using ab325675, the same antibody clone in a different buffer formulation.

Immunofluorescent analysis of 4% Paraformaldehyde-fixed, 0.1% TritonX-100 permeabilized Synchronized G1/S HeLa (human cervical adenocarcinoma epithelial cell), Synchronized G1/S HeLa cells treated with UV-C (100 J/m2) and then recovery for 1 hr and Synchronized G1/S HeLa cells treated with UV-C (100 J/m2) and then recovery for 1 hr and treated with phosphatase at 37℃ for 2h labelling Chk1 (phospho S345) with ab325675 at 1/500 (1.02 ug/ml) dilution, followed by ab150081 Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) preadsorbed antibody at 1/1000 (2 ug/ml) dilution (Green).

Confocal image showing increased nuclear staining in HeLa cells (shown in green) treated with UV-C (100 J/m2) and then recovery for 1 hr, and the signal decreased after phosphatase treatment at 37℃ for 2h. The counterstain was observed in magenta. Nuclear DNA was labelled with DAPI (shown in blue). Image was taken with a confocal microscope (Leica-Microsystems, TCS SP8).

ab7291 Anti-alpha Tubulin mouse monoclonal antibody was used to counterstain tubulin at 1/1000 (1 ug/ml) dilution, followed by ab150120 Goat Anti-Mouse IgG H&L (Alexa Fluor® 594) at 1/1000 (2 ug/ml) dilution (Magenta).
