“…However, affinity membranes with immobilized triazinic dyes have not achieved yet good acceptance in the biotechnological industry, mainly because of their low capacity for proteins in comparison with the same ligands immobilized on soft gels [31,32] and the dye leaching in the elution and regeneration steps [33]. Although, under equilibrium conditions, membranes show an acceptable chromatographic performance for Lf purification from bovine colostrum, better than the obtained with d-Sepharose, as a model of soft gels [34], the main problems affecting industrial utilization of adsorptive dye membranes, such as low capacity, dye leaching and pressure drop along the fiber axis need to be overcome. On the other side, the recovery of Lf from whey is a relatively difficult task, not only because the huge volume of whey needs to be dealt with, but also the major proteins complicate the separation process [22,35].…”

“…However, affinity membranes with immobilized triazinic dyes have not achieved yet good acceptance in the biotechnological industry, mainly because of their low capacity for proteins in comparison with the same legends immobilized on soft gels [24] and the dye leaching in the elution and regeneration steps [25]. Although, under equilibrium conditions, membranes show an acceptable chromatographic performance for Lf purification from bovine colostrums, better than the obtained with d-Sepharose, as a model of soft gels [26], the main problems affecting industrial utilization of adsorptive dye membranes, such as low capacity, dye leaching and pressure drop along the fiber axis need to be overcome. On the other side, the recovery of Lf from whey is a relatively difficult task, because not only the huge volume of whey needs to be dealt with, but also the major proteins complicate the separation process [27].…”

“…Służy temu np. adsorpcyjna chromatografia membranowa [20] oraz membranowa chromatografia powinowactwa [31]. W celu obniżenia kosztów otrzymywania LF próbowano także zastosować wstępną izolację LF z mleka za pomocą frakcjonowania z wytworzeniem piany [19].…”

“…przez zastosowanie adsorpcyjnej chromatografii membranowej, które pozwoliło na osiągnięcie wydajności odzysku laktoferyny powyżej 90 % [20]. Wykorzystanie membranowej chromatografii powinowactwa umożliwiło z kolei uzyskanie preparatów laktoferyny o czystości równej 94 % [31]. Preparat laktoferyny o zbliżonej czystości otrzymano także za pomocą magnetycznych wymieniaczy jonowych [5].…”
