Technical Data
Period Clock Protein 2 (Period 2, Period-2, Period 2 Isoform 1, Period Circadian Protein 2, Period Circadian Protein Homolog 2, Period Homolog 2, PER2, Circadian Clock Protein PERIOD2, Circadian Clock Protein PERIOD-2, FASPS, hPER2, KIAA0347)
PER2, a mammalian homolog of the Drosphilia period gene, shares 40% homology with PER1 including the protein dimerization PAS domain. A strong circadian rhythmic expression in the suprachiasmatic nuclei supports the view that the mammalian PER gene functions in the circadian clock with PER2 being a component of the circadian oscillator.

Suitable for use in Western Blot. Other applications not tested.

Recommended Dilution:
Western Blot: 1:1000
Optimal dilutions to be determined by the researcher.

Storage and Stability:
May be stored at 4C for short-term only. For long-term storage and to avoid repeated freezing and thawing, add sterile 40-50% glycerol, aliquot and store at -20C. Aliquots are stable for at least 12 months at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
