摘要：

背景：蛋白质的定量测定在各个领域中有着重要的意义。
目的：探讨血清蛋白浓度与共振散射光强度的关系。
方法：以405 nm的激发光波照射在四羧基酞菁锌与血清蛋白混合溶液上，共振散射光在475 nm处强度最强，Si-PIN光电探测器把475 nm的出射光信号转换成电压信号。
结果与结论：实验结果表明，2.0×10-4 mol/L四羧基酞菁锌与血清蛋白混合溶液的实验数据在10~50 g/L范围内线性关系良好，相关系数r=0.993 9，结果满意。

Abstract:

BACKGROUND: The quantitative determination of protein in various fields has important significance.
OBJECTIVE: To study the relationship between serum protein concentration and resonance scattering light intensity
METHODS: Excitation light irradiating of 405 nm was used on the mixture of Zn(II) tetracarboxy phthalocyanine and serum proteins solution. The resonance scattering light intensity was the strongest at 475 nm. The Si-PIN photodetector transformed the 475 nm light signals into voltage signals in order to study the relationship between voltage signal and protein concentration under certain conditions.
RESULTS AND CONCLUSION: The experimental data about the mixture of Zn(II) tetracarboxy phthalocyanine in 2.0×10-4 mol/L and serum proteins solution had good linear relationship within the range from 10 to 50 g/L and the correlation coefficient r=0.993 9. The results were satisfactory.
