居住区大气中铍卫生检验标准方法桑色素荧光分光光度法 - Was added , the absorption of morin at 350nm decreased and a new absorption peak at 419nm appeared . adding of nucleic acids to the morin - al binary system leads to decrease of the absorption at 350nm and great increase at 419nm . there is an isochromatic point at 370nm . the increase of absorbance at 419nm is proportional to the amount of nucleic acids added within certain concentration range . based on this , a new sensitive nucleic acids analysis method is established . the linear ranges of ct dna , fs dna and y rna are 0 . 7135 . 4 0 . 6425 . 6 and 0 . 9428 . 4g ml , respectively
铝离子的加入使桑色素350nm处的吸收峰下降,在419nm处出现桑色素-铝络合物的吸收峰。再往桑色素-铝离子二元体系中加入核糖核酸或脱氧核糖核酸,则进一步引起桑色素350nm吸收峰的降低， 419nm处的吸收大大加强,同时在370nm处有一等色点。 419nm处吸光度的增加值与加入的核酸量在一定范围内成正比,基于此建立了在较宽范围内测定核酸的方法。
