Quantitative und qualitative Untersuchungen der Esteraseaktivität in normalen Granulozyten, normalen Lymphozyten und in leukämischen Zellen

Summary

A quantitative and qualitative analysis of the carboxylic esterases of normal granulocytes, normal lymphocytes and leukemic cells was performed. In the myeloid leukemic cells and in the lymphatic leukemic cells, the esterase activity was significantly increased. By means of electrophoretic fractionation, four zones with esterase activity were detected in normal granulocytes and lymphocytes; the electrophoretic pattern of the leukemic cells was similar to that of the normal cells.
