Store at： 2～8°C
English name：ACHE；Acetylcholinesterase；Acetylcholine acetylhydrolase；Cholinesterase, Acetyl
CAS NO：9000-81-1
Grade：BR
Vitality：≥200units/g protein
Definition of enzyme activity unit ：Under the condition of 37 ℃, 0.1mol/l pH = 8.0 phosphate buffer, the amount of enzyme decomposing 1umol thioacetylcholine iodide (ATCI) per minute is one acetylcholinesterase activity unit.
Physicochemical properties (the following information is for reference only): Off white or brown powder.From the head of flies that are very sensitive to pesticides.Under certain conditions, organophosphorus and carbamates can inhibit the normal function of cholinesterase, and the inhibition rate is directly proportional to the concentration of pesticides,Under normal conditions, the enzyme catalyzes the hydrolysis of nerve conduction metabolite (acetylcholine), and its hydrolysate reacts with chromogenic agent to produce yellow substance. The change value of absorbance with time is measured by spectrophotometer to calculate the inhibition rate.The inhibition rate can be used to determine whether the product contains organophosphorus and carbamate pesticides.
Purpose: This product is only for scientific research and shall not be used for other purposes.(The following uses are for reference only) various instruments and spectrophotometer for detecting organophosphorus and carbamate pesticide residues in vegetables and fruits by enzyme inhibition rate method.
