STUDIES ON FERMENT ACTION : VI. THE RELATION OF IMMUNE SERUM LIPASE TO HEMOLYSIS.

1. The specific lipase of immune hemolytic serum is not necessary for hemolysis, but this does not prove the non-necessity of a lipolytic action in serum hemolysis, since a lipase is always present in the complement serum. 2. Serum lipase is found in the end-piece of split complement. 3. There is a parallelism between the lipase content and complement strength of the sera of different animals (man, rabbit, guinea pig, sheep, ox, cat).
