Whole cell lysates (15 µg) from the indicated cell lines were resolved by 4-12% Bis-Tris gel electrophoresis, transferred to a PVDF membrane, and probed with 1.0 µg/mL (1:500 dilution) purified anti-Chk1 antibody (clone P82G1D5) overnight at 4°C. Proteins were visualized by chemiluminescence detection using HRP goat anti-mouse IgG antibody (Cat. No. 405306) at a 1:3000 dilution. Direct-Blot™ HRP anti-GAPDH antibody (Cat. No. 607904) was used as a loading control at a 1:50000 dilution (lower). Lane M: Molecular weight marker.

    HeLa cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with methanol for 6 minutes, and blocked with 5% FBS for 30 minutes. Cells were then intracellularly stained with 5.0 µg/mL (1:100 dilution) purified mouse IgG2b, κ isotype ctrl antibody (Cat. No. 402201) (panel A) or purified anti-Chk1 antibody (clone P82G1D5) (panel B) overnight at 4°C, followed by incubation with Alexa Fluor® 594 goat anti-mouse IgG antibody (Cat. No. 405326) at 2.5 µg/mL. Nuclei were counter-stained with DAPI, and the image was captured with a 60X objective.

    Whole cell extracts (250 µg total protein) prepared from HeLa cells were immunoprecipitated overnight with 2.5 µg of purified mouse IgG2b, κ isotype ctrl antibody (Cat. No. 402201) or purified anti-Chk1 antibody (clone P82G1D5). The resulting IP fractions and whole cell extract input (10%) were resolved by 4-12% Bis-Tris gel electrophoresis, transferred to a PVDF membrane and probed with a control antibody raised against a separate epitope of Chk1.

Description

Checkpoint kinase 1, or Chk1, is a protein serine/threonine kinase that is an essential component of the ATR pathway, which links DNA abnormalities and double strand breaks to downstream signaling events. It is activated through phosphorylation by ATR at serine residues 345 and 317.  Once activated, Chk1 phosphorylates downstream effectors of S, G2, and M phases of the cell cycle to induce transcription regulation, energy consumption alterations, cell cycle arrest, and DNA repair. In cells challenged with excessive DNA damage, Chk1 activates apoptotic pathways. Chk1 inhibition is of therapeutic interest for multiple cancers due to synthetic lethality when pharmacological disruption of the protein is combined with radio- or chemosensitization.

Application

WB - Quality tested
ICC, IP - Verified
Recommended Usage

Each lot of this antibody is quality control tested by western blotting. For western blotting, the suggested use of this reagent is 0.05 - 1.0 µg/mL. For immunocytochemistry, a concentration range of 1.0 - 5.0 μg/mL is recommended. For immunoprecipitation, the suggested use of this reagent is 2.5 µg/test. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

This clone was tested for ICC on HeLa cells fixed with 4% PFA and permeabilized with either 100% methanol or Triton X-100. Both methods were compatible with Chk1 staining.
