The influence of serum albumin, ovalbumin and insulin on the absorption spectra of organic anions in solution is investigated in the visible range. The spectra of azo-dyes, phthaleins, indigosulphonates and anthraquinone dyes are affected in the same way by the three proteins: there is a general dep

## Abstract The binding of picrate, tropeolin, flavianate, naphthol orange, indigo di‐, tri‐and tetrasulphonate anions by serum albumin at pH 4.7 and 3.5 was determined by dialysis at 25°. It is shown that the experimental curves cannot be interpreted by the Scatchard equation and the Debye‐Hückel
