An investigation was made on the location of the factor in the phenomenon of leucolysis, influence of the heat, necessity of complement and the work of antigen and antibody to the leucocytes of different species.
1) Principal factor of the phenomenon of leucolysis exists in blood serum.
2) The factor of leucolysis is stable at 56.0 C for 30 minutes and it is considered to necessitate the complement.
3) In the existence of antigen and antibody, it was unable to lyse the leucocyte of different species, and species-specificity was recognized.
4) It is not to be considered that sensitized leucocytes are especially in a condition to cause lysis easily.
