Kinetics of haemolysis by complement. ii.--Development of new equations.

A new quantitative equation was developed by a process of trial and error. This equation, more complex than the classic Von Krogh equation, nevertheless gives a better account of percentages of haemolysis versus quantities of complement. A basic biological unit independent of red corpuscles quantity and sensitivity can be calculated. In addition, variations of the slope coefficient are of interest in pathology. However, the present paper is devoted to "normal" complement kinetics. Time-kinetics were found to follow the rules of general chemistry and could be derived mathematically.
