The Immunochemistry of Toxins and Toxoids

[摘要] The solubility of diphtherial toxoid has been determined on the acid side of its isoelectric point in methanol-water and water mixtures under controlled conditions of pH, ionic strength, protein concentration and temperature.On the basis of these studies, a three step method is presented for the preparation of purified diphtherial toxoid containing over 1500 Lf per mg of protein nitrogen.
