Abstract

A new rayleigh light scattering (RLS) assay of protein was conducted in this paper. The weak RLS of arsenazo III can be enhanced greatly by the addition of proteins. Based on this, the reaction of arsenazo III and proteins was studied. A new quantitative determination method for proteins has been developed. This method is very sensitive (0.085(021.25 μg/mL for BSA), rapid (<1min), simple (one step) and free of interference from most diverse substances.
