COMT (COMT, catechol-O-methyltransferase)
Description:
Catechol-O-methyltransferase catalyzes the transfer of a methyl group from S-adenosylmethionine to catecholamines, including the neurotransmitters dopamine, epinephrine, and norepinephrine. This O-methylation results in one of the major degradative pathways of the catecholamine transmitters. In addition to its role in the metabolism of endogenous substances, COMT is important in the metabolism of catechol drugs used in the treatment of hypertension, asthma, and Parkinson disease. COMT is found in two forms in tissues, a soluble form (S-COMT) and a membrane-bound form (MB-COMT). The differences between S-COMT and MB-COMT reside within the N-termini. The transcript variants are formed through the use of alternative translation initiation sites and promoters.

Positive Control: Human Testis lysate

Applications:
Suitable for use in ELISA (peptide) and Western Blot. Other applications not tested.

Recommended Dilution:
ELISA (peptide): 1:64000
Western Blot: 0.03-0.1ug/ml. ~ 28kD band and faint 25kDa band observed in Human Testis lysates (calculated MW of 30.0kD according to NP_000745.1 and 24.5kD according to NP_009294.1).
Optimal dilutions to be determined by the researcher.

Storage and Stability:
May be stored at 4C for short-term only. For long-term storage, 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.
