[Usage of the gel filtration method for the determination of urinary proteins (author's transl)].

The urinary proteins determination was carried out after purification by gel filtration over Sephadex rosin. The proteins eluaded react with Biuret-reagent to establish the coloured copper-proteins complex. If proteins concentrations is inferior, the proteins can be determinated by the copper-proteins complex isolation with second gel filtration and titrating Cu++ with reactives: dietildithiocarbamate or the PAR (4-(2pyridyl-azo)resorcinol monosodium salt).
