Product Overview
Clone ACCH-3 is a rabbit monoclonal antibody that recognizes circadian locomoter output cycles protein kaput (gene CLOCK) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF and flow cytometry. The predicted molecular weight is 95.3 kDa, and the supplier reports an observed band at about 85 kDa.
CLOCK is a transcription factor at the core of the mammalian circadian clock. Paired with BMAL1 (ARNTL), it activates E-box-containing genes such as PER and CRY, whose products feed back to repress CLOCK–BMAL1, generating roughly 24-hour rhythms; CLOCK also has histone acetyltransferase activity and is central to chronobiology research.

Samples with a confirmed band (WB): 293T cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Samples with confirmed staining (IHC): human thyroid carcinoma 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 CLOCK.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places circadian locomoter output cycles protein kaput in the nucleus and cytoplasm. Tissue expression noted by UniProt (human): Hair follicles (at protein level). The samples tested by the supplier (listed above) are a practical starting point for positive controls.
