ALBUMIN PREPARATION AND PROCESS FOR PRODUCING SAME

摘要

The present invention has been achieved in order to solve a problem that aggregates, which are considered to be caused by the aggregation of albumin, and contaminating proteins such as transferrin remain in an albumin preparation. Thus the present invention provides an albumin preparation wherein the content of aggregates determined by gel filtration is lower than the detectable limit and the content of transferrin determined by Mancini's method is lower than the detectable limit as well as a process for producing same which comprises treating an aqueous solution containing serum albumin with an anion exchanger, then with a ration exchanger and finally subjecting the solution to heat treatment.
