l-Arginine was used to suppress the aggregation of recombinant mink and porcine growth hormones in the refolding process from E. coli inclusion bodies by solubilization–dilution protocol at high protein concentration and pH 8.0. The influence of l-arginine concentration on the renaturation yield of both proteins was investigated. l-Arginine effectively suppressed the precipitation of growth hormones during dilution, but did not inhibit soluble oligomers formation. The results of mink and porcine growth hormones purification from 4 g of biomass are presented.
