Application of the Polarographic Effect of Proteins in Cancer Diagnosis

Nature volume 139, page 330 (20 February 1937) | Download Citation



THE investigations of E. Waldschmidt-Leitz1 have shown that blood serum, similarly to blood itself2, activates deactivated papain. Prof. E. Waldschmidt-Leitz1 has also shown that normal blood serum induces in these ferments or in methylglyoxalase a greater activity than serum from carcinomatic blood. This activity is ascribed to the sulphydryl groups of the proteins of serum.
