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.
