PCT No. PCT/SE85/00218 Sec. 371 Date Mar. 27, 1986 Sec. 102(e) Date Mar. 14, 1986 PCT Filed May 24, 1985 PCT Pub. No. WO85/05631 PCT Pub. Date Dec. 19, 1985.A method of purifying a contaminated product (protein/peptide) produced by rDNA technique, from hydrophobic contaminants which are charged and originate from the microbial cloning host employed, and the product thus purified are disclosed. The contaminated product is subjected to electroseparation, such as electrodialysis, to remove the contaminants. A charge-providing pretreatment is resorted to when the contaminants themselves are not charged enough to enable them to be directly separated upon electroseparation. In addition, a method of checking the purity of a product (protein/peptide) produced by rDNA technique is disclosed. Moreover, a method of checking the efficiency of the purification process used for purifying a product is disclosed. |
