Abstract

The process for producing the albumin preparation of the present invention comprises treating an aqueous albumin solution with an anion exchanger and a cation exchanger and subjecting the solution to heat treatment wherein a polyacrylamide type carrier having a cation exchange group is used as a cation exchanger. By using a polyacrylamide type carrier as a cation exchanger, the polymerization caused by the contaminating proteins can be suppressed, and a highly purified albumin preparation can be obtained.
