METHOD TO DELETE THE COLORATION OF THE HUMAN SERICA ALBUMINE.

摘要

A method for suppressing the coloration of human serum albumin expressed by genetic engineering, comprising the culture and / or purification in the presence of an amine compound selected from methylenediamine; propylenediamine; N, N-dialkyl (C1-6) alkylenediamines (C1-6); guanidines selected from guanidine, aminoguanidine and phenylguanidine; benzamidines selected from benzamidine and p-aminobenzamidine; and basic amino acids selected from lysine and arginine, in a proportion of 0.1 to 1% w / v with respect to the medium or the liquid fraction containing human serum albumin.
