- 应用备注
- Direct assays of acetylcholinesterase activity in blood, serum, plasma, and other biological samples. Evaluation of acetylcholinesterase inhibitors.
- 说明
-
1. This assay is based on an enzyme-catalyzed kinetic reaction. Addition of Working Reagent should be quick and mixing should be brief but thorough. Use of a multi-channel pipettor is recommended.
2. For assays in standard 1 mL cuvet, use 1 mL water and 1 mL Calibrator, 50 μL sample + 950 μL Working Reagent. - 实验流程
-
1. Calibrator: transfer 200 µL water and 200 µL calibrator separately into wells of a clear bottom 96-well plate. Samples: add 10 µL sample per well in separate wells.
2. Reaction: transfer 190 µL freshly prepared Working Reagent to all sample wells and tap plate briefly to mix. Read OD412nm at 2 min and at 10 min in a plate reader. - 试剂准备
-
The Working Reagent should be prepared freshly and used within 30 min. Each reaction well requires 2 mg reagent. Calculate the amount of reagent needed and weigh this amount (mg) in a centrifuge tube. Add 200 µL Assay Buffer per 2 mg reagent. Vortex to dissolve.
- 样品制备
-
Blood samples should be diluted 40-fold in the Assay Buffer, e.g. accurately pipet 5 µL blood and mix thoroughly with 195 µL Assay Buffer. Tissue or cell lysates are prepared by brief sonication or homogenization in 0.1M phosphate buffer (pH
7.5), followed by centrifugation at 14,000 rpm for 5 min. Use supernatant for assay. Ideally samples should be assayed fresh. If this is not possible, refrigerate samples and assay them within 24 hours. - 限制

- 背景
-
Quantitative determination of acetylcholinesterase activity by colorimetric (412nm) method.
Procedure: 10 min.
Acetylcholinesterase (EC 3.1.1.7, AChE), also known as RBC cholinesterase, is found primarily in the blood and neural synapses. Low serum cholinesterase activity may relate to exposure to insecticides or to one of a number of variant genotypes. AChE catalyzes the hydrolysis of the neurotransmitter acetylcholine into choline and acetic acid, a reaction necessary to allow a cholinergic neuron to return to its resting state after activation. Cholinesterase levels of cells and plasma are used as a guide in establishing safety precautions relative to exposure and contact, as well as a guide in determining the need for workers to be removed from areas of contact with the organic phosphate insecticides. Simple, direct and automation-ready procedures for measuring AChE activity are very desirable. This Acetylcholinesterase Assay is based on an improved Ellman method, in which thiocholine produced by the action of acetylcholinesterase forms a yellow color with 5,5'-dithiobis(2-nitrobenzoic acid). The intensity of the product color, measured at 412 nm, is proportionate to the enzyme activity in the sample.
