Anti-Chk1 Antibody

Manufactured by Antibodies.com as part of their Primary Antibodies portfolio, this polyclonal reagent is raised in Rabbit and targets endogenous levels of the Chk1 kinase. The antibody is supplied as a 50 µl liquid formulation at 1 mg/ml in PBS containing 50% glycerol, 0.5% BSA and 0.02% sodium azide, and is unconjugated so it can be paired with the secondary detection system of the user's choice. Validated applications include Western blotting (WB) and ELISA, making it suitable for protein-level confirmation of Chk1 expression in cell lysate or tissue-derived samples. The immunogen is a synthesized peptide derived from human Chk1 around the non-phosphorylation site of S280, and the antibody has been affinity-purified from rabbit antiserum by affinity-chromatography using the epitope-specific immunogen to minimise non-specific binding. Reactivity has been characterised for Human samples, while clonality is reported as Polyclonal, providing broader epitope coverage that is generally more tolerant of minor antigen variations between experimental batches. For long-term stability, the product should be stored at -20 °C, and the manufacturer recommends use within one year under those conditions. The reagent is intended for research use only and is not validated for diagnostic or therapeutic applications; it is dispatched from Stockholm, Sweden, with a typical lead time of 5–8 business days.
