Descrição detalhada : The Acetylcholinesterase Activity Assay Kit (Colorimetric) provides a simple, quick, and direct procedure for measuring Acetylcholinesterase levels in a variety of samples such as serum, plasma, tissues or cell lysates / cell extracts. This assay is based on the Ellman method in which thiocholine, produced by Acetylcholinesterase, reacts with DTNB 5,5¢-dithiobis (2-nitrobenzoic acid) to form a colorimetric product (412 nm), proportional to the Acetylcholinesterase activity present. This kit does not require weighing, or mixing of multiple reagents. The Acetylcholinesterase activity is measured without the use of a calibration curve. The Acetylcholinesterase Positive Control in the kit can be used to screen for Acetylcholinesterase inhibitors. The detection range: 10-600 units/liter of Acetylcholinesterase activity.The detection time: 5-10 minutesAcetylcholinesterase ( AChE) is a serine hydrolase found at neuromuscular junctions and cholinergic brain synapses. AChE, hydrolyzes choline esters. Acethlcholinesterase activity is related to the function of the nerve response. Its principal biological role is the termination of impulse transmission at cholinergic synapses by rapid hydrolysis of the neurotransmitter acetylcholine (ACh) to acetate and choline.Organophosphorus (OP) poisons form a covalent bond with a serine residue at the active site of AChE, and are thus potent irreversible inhibitors of AChE.AChE inhibitors are used in treatment of various neuromuscular disorders, and have provided the first generation of drugs for the treatment of Alzheimer's disease.AChE inhibitors inhibit the cholinesterase enzyme from breaking down ACh, increasing both the level and duration of the neurotransmitter action According to the mode of action, AChE inhibitors can be divided into two groups: irreversible and reversible. Reversible inhibitors, competitive or noncompetitive, mostly have therapeutic applications, while toxic effects are associated with irreversible AChE activity modulators.
