摘要
用PEG2000双水相萃取、DEAE-SephadexA-50和SephadexG-200方法分离纯化麦穗鱼Pseudorasboraparva脑中的乙酰胆碱酯酶(AChE),并制备了兔抗麦穗鱼脑AChE抗血清。用兔抗麦穗鱼脑AChE抗体连接抗原,建立了定量分析麦穗鱼脑AChE的间接非竞争酶联免疫吸附法(Indirectandnon-competitiveELISA),此法操作简便、灵敏度高,适用于定量检测。该方法的建立有利于AChE在环境科学和农药学研究领域的进一步研究和应用。
Acetylcholinesterase (AChE) was purified from the brain tissues of topmouth gudgeon (Pseudorasbora parva) by PEG 2000/phosphate salt with two phases extraction, DEAESephadex A50 and Sephadex G200 chromatography, and rabbit antiAChE antibody was made. Using rabbit antiAChE antibody reacting with the brain AChE of topmouth gudgeon, indirect noncompetitive ELISA was established to quantify the brain AChE of topmouth gudgeon. The method was easy to operate with high sensitive. The establishment of the method will be helpful for environmental pesticide science.
