Product Overview
Clone FOF-3 is a rabbit monoclonal antibody that recognizes serine/threonine-protein kinase Chk2 (gene CHEK2) in human samples and is validated for Western blot, IHC, ICC/IF and immunoprecipitation. The predicted molecular weight is 60.9 kDa, and the supplier reports an observed band at about 62 kDa.
Chk2 (CHEK2) is a serine/threonine kinase activated by ATM in response to DNA double-strand breaks. It phosphorylates targets such as p53, CDC25 phosphatases and BRCA1 to promote cell cycle arrest, DNA repair or apoptosis, and inherited CHEK2 variants are associated with increased cancer risk.

Samples with a confirmed band (WB): HeLa cells, 293T cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Samples with confirmed staining (IHC): human testis tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Samples with confirmed staining (ICC/IF): HeLa cells.
Immunogen
Synthetic peptide based on the sequence of human chk2.
Reactivity Notes
The supplier lists reactivity with human. Tissue expression noted by UniProt (human): High expression is found in testis, spleen, colon and peripheral blood leukocytes. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
