CLOCK Antibody (PA1-520) in ICC/IF

Immunofluorescent analysis of CLOCK (green) showing staining in the nucleus and cytoplasm of U251 cells (right) compared to a negative control without primary antibody (left). Formalin-fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 5-10 minutes and blocked with 3% BSA-PBS for 30 minutes at room temperature. Cells were probed with a CLOCK polyclonal antibody (Product # PA1-520) in 3% BSA-PBS at a dilution of 1:100 and incubated overnight at 4 ºC in a humidified chamber. Cells were washed with PBST and incubated with a DyLi... View More

Product Specific Information

PA1-520 detects CLOCK from human, mouse, rat and hamster tissues.

PA1-520 has been successfully used in Western blot, ICC/IF and immunohistochemistry procedures. By Western blot, this antibody detects an ~100 kDa protein representing CLOCK from rat brain homogenate. Immunohistochemical staining of CLOCK in hamster brain with PA1-520 results in the staining of the superchiasmatic nucleus.

PA1-520 immunizing peptide corresponds to amino acid residues 11-30 of mouse CLOCK. This sequence is completely conserved between mouse and human CLOCK. PA1-520 immunizing peptide (Cat. # PEP-072) is available for use in neutralization and control experiments.

Target Information

This gene encodes a protein that belongs to the basic helix-loop-helix (bHLH) family of transcription factors. Polymorphisms within the encoded protein have been associated with circadian rhythm sleep disorders. A similar protein in mice is a circadian regulator that acts as a transcription factor and forms a heterodimer with aryl hydrocarbon receptor nuclear translocator-like to activate transcription of mouse period 1.
