PER2 ELISA kits are immunoassay tools for the measurement of the protein period circadian regulator 2, which is encoded by the PER2 gene in humans. Functionally, this protein is known to be a transcriptional repressor which forms a core component of the circadian clock. The canonical protein structure is reported to have an amino acid sequence of 1255 residues and a mass of 136.6 kDa. It is known to be localized in the nucleus and cytoplasm and is widely expressed across many tissue types. As many as 2 protein isoforms have been reported. The protein has been noted to be post-translationally ubiquitinated, acetylated and phosphorylated. The PER2 gene has been associated with the disease, Advanced sleep phase syndrome. Other alias names for this target include FASPS1, period circadian protein homolog 2, circadian clock protein PERIOD 2, hPER2, period 2, and FASPS.
There are PER2 ELISA kits that can detect a target at concentrations as low as 15 ng/L and as high as 20 ng/mL. Click on the products below for more detailed ELISA kit information, such as target reactivity and assay sensitivity.
