Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. Please refer to for technical protocols.
  3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.

Circadian rhythms are behavioral or physiological rhythms with periods of approximately 24 hours. They have been identified in many species from bacteria to humans. In mammals, the circadian regulator is the suprachiasmatic nucleus (SCN) of the anterior hypothalamus. Multiple genes involved in the SCN circadian rhythm have been isolated. The Drosophila period (dper) gene is the most completely characterized mammalian clock gene. In mouse, multiple per genes have been identified and constitute a mammalian period gene family (mper1, mper2, and mper3). These proteins contain a dimerization PAS domain and a cytoplasmic localization domain. SCN expression of mper1 and mper2 overlaps,  but is not synchronous. Although not light-inducible, mper2 transcripts are detected approximately two hours following those of mper1. This suggests that the mper1 gene product, a putative transcription factor, is produced in response to light and promotes the expression of mper2. Although mper1 and mper2 are similar, they are not redundant. Thus, these different circadian regulators may allow integration of a wider range of input signals and interact with different downstream effectors.

Tissue culture supernatant is purified by either protein A/G or affinity purification methods. Both methods yield antibody in solution that is free of most other soluble proteins, lipids, etc. This format provides pure antibody that is suitable for a number of downstream applications including: secondary labeling for flow cytometry or microscopy, ELISA, Western blot, etc.
