    摘要: A method for decoloring a recombinant human serum albumin by treating the albumin with a reducing agent is disclosed. Also, a method for decoloring a recombinant human serum albumin by treating the albumin with a method removing free polysaccharides with a cation exchanger followed by heat treatment is disclosed. The present invention provides a recombinant human serum albumin, coloring of which is fully suppressed by preventing binding of certain coloring components, which are contained in the raw materials or contaminants secreted by a microorganism, to human serum albumin so as not to cause coloring of the human serum albumin.

    摘要: A method for highly purifying human serum albumin (HSA), which comprises bringing a fraction containing HSA produced by genetic engineering into contact with a chelating chromatography carrier bound with copper ions, and eluting the HSA adsorbed by the carrier with a buffer containing ammonium chloride as an atagonist and having a pH of about 5-7.According to the method of the present invention, a component derived from yeast, which cannot be sufficiently removed by conventional purification methods for HSA produced by genetic engineering, can be removed from HSA produced by genetic engineering, and a highly purified HSA can be provided.
