| catechol oxidase | A type 3 copper protein that catalyses exclusively the oxidation of catechol (i.e., o-diphenol) to the corresponding o-quinone. The enzyme also acts on a variety of substituted catechols.It is different from tyrosinase, EC 1.14.18.1, which can catalyse both the monooxygenation of monophenols and the oxidation of catechols. Group: Enzymes. Synonyms: diphenol oxidase; o-diphenolase; polyphenol oxidase; pyrocatechol oxidase; dopa oxidase; catecholase; o-diphenol:oxygen oxidoreductase; o-diphenol oxidoreductase. Enzyme Commission Number: EC 1.10.3.1. CAS No. 9002-10-2. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C. Form: Liquid or lyophilized powder.

| Methamphetamine (BSA) | Methamphetamine (METH) is closely related chemically to amphetamine (AMPH). METH is a potent central nervous system stimulant with additional peripheral sympathomimetic effects. METH and AMPH have been used clinically in the treatment of obesity, minimal brain dysfunction, narcolepsy, depression and to counter fatigue. They are also subjected to widespread abuse. METH is an indirect agonists. It causes the release of newly synthesized norepinephrine and dopamine and it blocks the re uptake of these transmitters from the synapse. This can lead to an increase in the concentration of catecholamines in the synapse as well as an overall increase in catecholaminergic activity in the brain. The mechanism of METH induced neurotoxicity for all monoaminergic cell types may lie primarily with the dopaminergic system in the striatum. It may also lie with the interaction between METH induced release of dopamine and its ability to inhibit monoamine oxidase. Group: Biochemicals. Grades: Highly Purified. Pack Sizes: 1mg.

| Native Bovine Plasma Amine Oxidase | Amine oxidase (also known as histaminase) is an enzyme involved in the metabolism, oxidation, and inactivation of histamine within the digestive tract. Bovine plasma amine oxidase has a molecular weight of 170 kDa and an optimum pH of 6.2 for spermine and 7.2 for spermidine. Amine oxidases are divided into two classes:the pyridoxal and copper containing enzyme to which plasma amine oxidase belongs, and the FAD-containing amino oxidases. Natural substrates include catecholamines, tryptamine derivatives and other physiologically active amines. Plasma amine oxidase is used in research requiring nitrogen group transfers. The molecule is composed of two identical polypeptide chai...mM respectively).

| Native Mushrooms Polyphenol Oxidase | Polyphenol oxidase is a tetramer that contains four atoms of copper per molecule, and binding sites for two aromatic compounds and oxygen. The enzyme catalyses the o-hydroxylation of monophenol molecules in which the benzene ring contains a single hydroxyl substituent) to o-diphenols (phenol molecules containing two hydroxyl substituents). It can also further catalyse the oxidation of o-diphenols to produce o-quinones. PPO causes the rapid polymerization of o-quinones to produce black, brown or red pigments (polyphenols) that cause fruit browning. The amino acid tyrosine contains a single phenolic ring that may be oxidised by the action of PPOs to form o-quinone. Hence, PPOs may also be referred to as tyrosinases. Polyphenol oxidase (tyrosinase) is a bifunctional, copper-containing oxidase having catecholase and cresolase activity. a lyophilized powder. store at -20°c. Group: Enzymes.
