All lanes : Anti-CHK1 Antibody (D440) at 1:2000 dilution Lane 1: CCRF-CEM whole cell lysate Lane 2: Hela whole cell lysate Lane 3: mouse colon lysate Lysates/proteins at 20 µg per lane. Secondary Goat Anti-Rabbit IgG, (H+L), Peroxidase conjugated at 1/10000 dilution. Predicted band size : 54 kDa Blocking/Dilution buffer: 5% NFDM/TBST.

Formalin-fixed and paraffin-embedded human cancer tissue reacted with the primary antibody, which was peroxidase-conjugated to the secondary antibody, followed by DAB staining. This data demonstrates the use of this antibody for immunohistochemistry; clinical relevance has not been evaluated. BC = breast carcinoma; HC = hepatocarcinoma.

Rabbit Polyclonal Antibody to CHK1

Description
Checkpoint pathways control the order and timing of cell cycle transitions and ensure that critical events, such as DNA replication and chromosome segregation, are completed with high fidelity. Antibodies against CHK1 recognize a 54-kD protein on immunoblots of mammalian cell extracts, but the protein has altered mobility when isolated from cells treated with ionizing radiation (IR), indicating that CHK1 is modified in response to DNA damage. In vitro, CHK1 directly phosphorylates a regulator of CDC2 tyrosine phosphorylation, CDC25C. Evidence indicates that in response to DNA damage, CHK1 phosphorylates and inhibits CDC25C, thus preventing activation of the CDC2-cyclin B complex and mitotic entry. Proteolysis of activated CHK1 may promote checkpoint termination under normal conditions and may play a role in the cytotoxic effects of camptothecin and related anticancer drugs.
