WebHeat inactivation has previously been shown to increase the reactivity of many pathological sera when tested for complement-fixing immune complexes. The mechanism of this effect has been presumed to be inactivation by heat of endogenous complement already bound to immune complexes. WebHeating serum at 56° is used to inactivate complement in several immunological assays. During heating, both heat-labile and heat-stable anticomplementary activity (ACA) develop. While heat-labile ACA can be completely inactivated, heat-stable ACA increases progressively with continued heating. Heat-stable ACA develops in deaggregated IgG and ...
