In the biochemical analysis aspect, it is first time to use the simple fluorescence spectrophotometer to determine the protein in human serum by red alizarin as the probe of the RLS. The experiment shows that the system HSA-red alizarin has the maximum intensity of the RLS in Britton-Robison buffer of pH4.10 at maximum wavelength of about 360nm. The method has better linear range within 0.040-10.0ug/mL, determination limit is 0.040ug/mL. Moreover, We have selected three other dyes of chromotrope 2R, acid chrome dark blue and pyrocatechin violet as the probes of the RLS in determining protein in human serum and achieving satisfactory results.

在生化分析方面，作者首次使用简易960型荧光分光光度计，利用茜素红作为共振光散射光谱探针对人血清中的蛋白质含量进行了测定，测定结果显示在pH4.10的Britton-Robinson缓冲溶液，波长360nm处出现最大的共振光散射强度，其线性范围为0.040～10.0μg／mL，检出限为0.040μg／mL；另外，作者还筛选了其他三种可用作蛋白质测定的共振光散射光谱探针的有机染料：变色酸2R、酸性铬深蓝、邻苯二酚紫，并深入研究了测定的适宜条件和干扰情况，将这三种有机染料用于人血清中蛋白质含量的测定，均取得了满意结果。
