Anti-Chk1 (Ab-317) Antibody

Checkpoint Kinase 1 (Chk1) is a serine/threonine kinase central to the DNA damage response, driving S-phase and G2/M checkpoint signalling in human cells. This polyclonal antibody from Antibodies.com, raised in rabbit and identified by the Ab-317 designation, is supplied as 100 µl of unconjugated, affinity-purified antiserum and is intended for the study of Chk1-dependent processes in cell culture and tissue contexts.

Validated for Western blot and immunohistochemistry, the reagent produces the nuclear staining pattern expected of an antibody directed against the endogenous Chk1 target on human samples. Each vial is shipped in a stabilizing buffer; aliquot on arrival and store at -20 °C, avoiding repeated freeze-thaw cycles, with working dilutions held at 4 °C protected from light for short-term use. Supplied for research use only, the reagent is not validated for diagnostic or therapeutic work.
