目前我国胆碱酯酶活力的测定一般采用羟胺-三氯化铁比色法。由于基质(氯化乙酰胆碱)容易吸水,给准确称量带来困难;贮备基质水溶液,又因基质容易水解,浓度下降。因此,尽管文献对基质作了严格规定,但终因现在市售氯化乙酰胆碱最小包装为1克,一般短期很难用完,将给以后实验 At present, the determination of cholinesterase activity in our country generally use hydroxylamine - ferric chloride colorimetric method. As the substrate (acetylcholine chloride) easy to absorb water, to accurately weigh the difficulties; reserve matrix aqueous solution, but also because of matrix hydrolysis, the concentration decreased. Therefore, despite the literature on the substrate made strict rules, but at the end of the current commercial minimum supply of acetylcholine 1 g, generally difficult to run out in the short term, will give later experiments
