The order of reaction in immune hemolysis is C’1, C’4, C’2, C’3, C’5, C’6, C’7, C’8, C’9
The first component, C’1 is a complex of 3 protein subcomponents C’1q, C’1r, and C’1s, held together by calcium ions
Activation proceeds in a cascade-like fashion: i.e.; each component is activated by the preceding one and, in turn, leads to the activation of the next component in the sequence
