Technical Data
Period Clock Protein (dPER)
Several endogenous factors have been linked to rhythmicity or circadian behavior of living organisms. In Drosophila, the genes period (dPer) and timeless (tim), and Neurospora frequency (frq), have been proposed to be responsible for their circadian rhythm. Drosophila Period clock protein is involved in the generation of biological rhythms. It interacts with Timeless protein (Tim). dPER first accumulates in the perinuclear region about an hour before it is transported to the nucleus. It contains a remarkable run of alternating Gly-Thr residues.

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

Synthetic peptide corresponding to 21aa within the C-terminus of Drosophila Period Clock Protein 1, conjugated to KLH.
Supplied as a liquid with PBS, 0.05% sodium azide
Recognizes Drosophilla Per. The epitope is conserved in various alternatively spliced forms of dPer (dPerA, dPerB, etc.). Species Crossreactivity: Drosophilla peptide sequence has no sequence homology with mammalian PER or Clock proteins.
Intended for research use only. Not for use in human, therapeutic, or diagnostic applications.
