Technical Data
C7851-70C
COMT (Catechol-O-Methyltransferase)
Description:
Applications:
Suitable for use in ELISA and Western Blot. Other applications not tested.

Recommended Dilution:
Peptide ELISA: 1:8000
Western Blot: 0.3-1ug/ml ~26kDa plus 29kDa bands observed in Human Testis lysates (calculated MW of 30.0kDa according to NP_000745.1 and of 24.5kDa according to NP_009294.1). Optimal dilutions to be determined by the researcher.

Storage and Stability:
May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.

Peptide Blocking:
Corresponding peptide is available for Peptide Blocking studies. See C7851-70C-P. Antibody is typically 0.5mg/ml and peptide is supplied as a 100ul pellet. When peptide is reconstituted in 200ul water, the concentration would also be 0.5mg/ml. To start, the best ratio would be 1:1 (molar excess of peptide relative to antibody when identical volumes are mixed). Mix equal volumes of peptide and antibody at the required dilution and leave at ambient temperature. It is best is to have two identical blots to be incubated with equal amount of antibody, but one with the antibody pre-adsorbed to the peptide for 20min. Then incubate and develop the two blots in parallel.

Concentration:
~0.5mg/ml
Immunogen:
Synthetic peptide corresponding to GDTKEQRILNHVLQC, from the N Terminus of human COMT (NP_000745.1; NP_001128633.1; NP_001128634.1; NP_009294.1)
Purity:
Purified by affinity chromatography.
Form
Supplied as a liquid in Tris saline, pH 7.2, 0.5% BSA, 0.02% sodium azide.
Specificity:
Recognizes human COMT. Species sequence homology: mouse, rat and canine. This antibody is expected to recognise both reported isoforms. Variants (NP_000745.1; NP_001128633.1; NP_001128634.1) encode the same isoform.
Intended for research use only. Not for use in human, therapeutic, or diagnostic applications.
