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.
