| Several endogenous factors have been linked to rhythmicity or circadian behavior of living organisms. In Drosophila, the genes period (dPer) and timeless (tim), and in Neurospora frequency (frq), have been proposed to be responsible for their circadian rhythm. Recently human and mouse genes encoding a basic helix-loop-helix (bHLH) and Per-ARNT-Sim (PAS)-domain with significant similarity to the Drosophila Period have been reported. The cDNA sequences of hPER and mPer1 (also named RIGUI) are predicted to encode for proteins of length 1290 and 1291 amino acids respectively. Homologues of mPer1 designated Per 2 (1257aa) and Per3 (1113aa) have also been cloned. Both Per1 and Per2 levels show circadian rhythm in the SCN and eyes. It has been suggested that mPer regulates neuronal activity in the SCN. Mouse Clock (855 aa) is abundantly expressed in brain (SCN, pyrifom cortex, hippocampus) as well as in other tissues (eye, total brain, tested, ovaries, liver, heart, lung, and kidney). Although, Clock is constitutively expressed (not rhythmic) in the SCN, it may still be an important component of circadian machinery. Basic-helix-loop-helix-PAS orphan protein, MOP3 (Members Of PAS Superfamily, also known as BMAL1/JAP3/PAS3, 626aa) is a general dimerization partner for several PAS superfamily of transcription regulators. MOP3 interacts with MOP4 (also known as NPAS2, 626aa), Clock, HIF1a, and HIF2a. MOP4 is a brain specific homolog of Clock. Applications: Suitable for use in ELISA. Western Blot, though not tested, may potentially be used as an application. Other applications not tested. Recommended Dilution: Western Blot: 1:1000-1:5000 ELISA: 1:10,000-1:100,000 using 50-100ng of control peptide/well. Optimal dilutions to be determined by the researcher. Control Peptide: M4590-03 MOP3 Control Peptide Storage and Stability: May be stored at 4C for short-term only. For long-term storage, 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. |
