Claims (15)

1. Способ удаления необычных трансмиссивных агентов (NCTA) из белкового раствора, отличающийся тем, что в растворе белка, чувствительного к загрязнению NCTA, суспендируют по меньшей мере один адсорбент, выбранный из группы, состоящей из кизельгура, диатомовой земли, кремниевой кислоты, глинистых минералов, гидроксида металла, оксигидрата металла, целлюлозы, перлита, бентонита и нерастворимых в воде синтетических полимеров, в течение времени по меньшей мере 10 мин, в течение которого полученную суспензию перемешивают, и затем адсорбент отделяют от белкового раствора.1. A method of removing unusual transmissible agents (NCTA) from a protein solution, characterized in that at least one adsorbent selected from the group consisting of kieselguhr, diatomaceous earth, silicic acid, clay minerals is suspended in a protein solution sensitive to contamination of NCTA , metal hydroxide, metal oxyhydrate, cellulose, perlite, bentonite and water-insoluble synthetic polymers, for at least 10 minutes, during which the resulting suspension is stirred, and then the adsorbent is separated from protein solution. 2. Способ по п. 1, при котором адсорбент отделяют от раствора белка, чувствительного к загрязнению NCTA, центрифугированием или фильтрованием. 2. The method of claim 1, wherein the adsorbent is separated from the protein solution sensitive to NCTA contamination by centrifugation or filtration. 3.

The method according to one of paragraphs. 1-11, in which one or more parameters of the solution change at least once during the period of contact of this solution with the adsorbent. 13. Способ по п. 12, в котором параметрами раствора являются температура, концентрация одного или нескольких растворенных веществ и ионная сила. 13. The method according to p. 12, in which the parameters of the solution are temperature, the concentration of one or more dissolved substances and ionic strength. 14. Способ по одному из п. п. 1-13, при котором время контакта раствора с адсорбентом заключено в диапазоне 3 мин - 48 ч, например, между 30 мин и 12 ч или между 3 ч и 48 ч. 14. The method according to one of p. 1-13, in which the contact time of the solution with the adsorbent is in the range of 3 minutes - 48 hours, for example, between 30 minutes and 12 hours or between 3 hours and 48 hours 15. Способ по одному из пп. 1-13, при котором температура белкового раствора заключена в диапазоне 0-20oС и предпочтительно равна примерно 2oС.15. The method according to one of paragraphs. 1-13, at which the temperature of the protein solution is in the range of 0-20 o C and preferably equal to about 2 o C.
