FIELD: chemistry; biochemistry. ^ SUBSTANCE: invention pertains to bioengineering. The method involves successive steps for ultrafiltration of a first antibody preparation to obtain a second antibody preparation, diafiltration of the second antibody preparation to obtain an intermediate preparation and second ultrafiltration of the intermediate preparation to obtain a third antibody preparation. All steps are carried out at temperature ranging from approximately 30C to approximately 50C. ^ EFFECT: design of an efficient method of concentrating antibody preparations. ^ 52 cl, 25 dwg, 25 tbl, 12 ex |
