摘要
对蛋白酶A的荧光检测方法进行了研究。分析了标准蛋白酶A稀释液对标准曲线建立的影响、检测方法的稳定性及检测时间对样品结果的影响。并对蛋白酶A酶活力与荧光值的相关性进行了分析,证明了在同一批样品检测中蛋白酶A酶活与对应的荧光值具有很好的相关性,可以根据荧光值的大小直接判断和比较蛋白酶A活力的高低。
In this paper, the fluorescent detection method of protease A was studied. The effects of standard protease A dilution on the establishment of standard curve were analyzed, and the effects of the detection method stability and detection time on sample testing results were investi- gated. Besides, the relevance ofprotease A activity and fluorescence values was analyzed. The results showed that protease A activity in the same batch of samples had good correlations with the corresponding values of the fluorescence. Accordingly, protease A activity could be judged and compared based on the values of fluorescence.
