摘要
从鸡肝中提取的DNA具有酯酶活性.实验结果表明α或β萘酯能被此DNA水解,从而导致坚牢蓝RR盐出现特征性的紫红色,以及在O.D540nm处引起吸收值的增加.
DNA which extracted from liver in G. gallus domesticuv exhibited esterase activity. The experimental results suggested that α-naphtyl or β-naphtyl acetate could be decomposed by the DNA and then fast blue RR salt be led to appear special violet colour with increasing O. D540nm.
