Scientific Background
Monoamine Oxidases (MAO) catalyze the oxidation of monoamines such as dopamine, serotonin and adrenalin. They are found bound to the outer membrane of mitochondria in most cell types in the body. Two subtypes of monoamine oxidase have been identified: MAO-A and MAO-B. Both are found in neurons and astroglia, with MAO-A also found in the liver, gastrointestinal tract and placenta and MAO-B in blood platelets. Abnormal regulation of MAOs in the body has been associated with depression, substance abuse, attention deficit disorder, and irregular sexual maturation. Mutation of this gene results in Brunner syndrome.

Safety & Handling
Avoid freeze/thaw cycles.
This protein was produced in Insect Cells (Sf9). Expression system selection determines post-translational processing, disulfide bond formation, and co-factor incorporation — all of which affect enzymatic activity. Insect cell (Sf9) systems are preferred for kinases and multi-subunit enzymes that require phosphorylation or chaperone assistance; E. coli is used for structurally simpler proteins.
This protein spans amino acids 2-497. Confirm the region includes your domain of interest — the active site, binding pocket, or substrate recognition sequence — before placing your order. Refer to the UniProt database for domain annotation.
Purity is assessed by SDS-PAGE; see the Certificate of Analysis. A gel image is provided with each lot. BPS Bioscience performs rigorous QC on each lot, including purity assessment and functional activity testing where applicable. Contact technical support if purity ≥99% is required for biophysical measurements.
Suitable for protein binding studies, as an immunogen, or as a protein standard for Western blotting. Refer to the product datasheet for validated protocols and recommended assay conditions. Contact BioHippo technical support for application-specific guidance.
At least 6 months at -80°C. Avoid repeated freeze-thaw cycles — prepare single-use working aliquots. Add BSA or glycerol to aliquots if storing diluted enzyme is necessary. Typical stability is at least 6 months at −80°C.
