Studies on Naturally Occurring Warm Haemolysins and Haemagglutinins Active against Trypsinized Red Cells

Abstract

A normal serum with haemolytic and agglutinating activity against trypsintreated red blood cells at 37°C has been studied. The properties of this serum appear to be very similar, if not identical, to those of the warm haernolysin described by HEISTO et al. [l].
