“…Although chromatographic separations have been the workhorse of most purification processes, several limitations have been pointed out, such as (i) batch operation, (ii) low capacity, (iii) complex scale-up, (iv) time-consuming and high pressure packing processing, (v) slow intraparticle diffusion, (vi) low chemical and proteolytic stability and consequent contamination of the final product, and (vii) the high cost of the resins [5][6][7][8][9]. The replacement of some of these chromatographic steps by non-chromatographic alternatives, with high capacity and throughput, has been then suggested [7,[10][11][12].…”

“…Nonchromatographic alternatives including membrane chromatography, tangential flow filtration, high gradient magnetic fishing, aqueous two-phase extraction, precipitation, and crystallization have also been described (Przybycien et al, 2004;Low et al, 2007;Azevedo et al, 2009).…”

“…Układ trójfazowy tworzy się zwykle po dodaniu tert-butanolu (t-butanolu) do wodnego roztworu mieszaniny białek (w której znajduje się separowane białko), a następnie siarczanu amonu [6]. Celem tej metody jest wytrą-cenie separowanej substancji (składnika mieszaniny) w interfazie (fazie środkowej), tworzącej się pomiędzy górną fazą organiczną a dolną nieorganiczną (będącą wodnym roztworem soli) lub preferencyjne przeprowadzenie separowanej substancji do fazy dolnej z jednoczesnym strąceniem pozostałych białek w interfazie [21].…”
