| Abstract: | The chemical characteristics of 6 batches of the preparation, obtained from the cell wall of C. diphtheriae grown in liquid and solid culture media, with respect to their content of nitrogen, hexoses, pentoses, total amino sugars, lipids and to the possible admixture of nucleic acids are presented. From the results of the chemical analysis of these batches their standardization according to the ratio of total amino sugars and pentoses to total nitrogen in C. diphtheriae cell-wall preparation is proposed. |
