Application of method of quantification for protein by biuret reaction to determine the pharmaceutical pepsin activity

ABSTRACT

Method of improved pp biuret with high sensitivity and accuracy is frequently used in the biochemical techniques to determine the protein in the preparations. The sensitivity of this method was as same as this of method Anson and error of pp biuret was smaller than this of Anson. The pp biuret has been applied in Vietnam to determine the proteolytic activity of pharmaceutical pepsin.
