Rat Period Circadian Protein 2 (PER2) ELISA Kit

The Period Circadian Protein 2 (PER2) is a core transcriptional regulator of the mammalian circadian clock, expressed in the suprachiasmatic nucleus and peripheral tissues of rats. This Assay Genie ELISA Kit enables quantitative measurement of PER2 protein in rat tissue homogenates, with absorbance-based readout on a 96-assay well plate format suitable for chronobiology, sleep research, and circadian gene expression studies.

Investigators profiling diurnal hormone cycles, shift-work disruption models, or photic entrainment paradigms can apply the kit to track PER2 abundance across 24-hour time courses in hypothalamus, liver, or kidney extracts. The workflow fits standard in vitro laboratory schedules and supports reproducible quantification in rodent tissue samples.

Each kit ships with pre-coated wells, conjugate, standards, and the buffer reagents required to run the full plate. Intended for research use only, the assay targets a clock-gene product linked to seasonal affective responses, metabolic timing, and tumor-suppressor pathways in rat models.
