A simplified quantification method of complex-release activity using peroxidase as immune complex antigen.
The complement-mediated solubilization of precipitable immune complexes (complex-release activity) in serum specimens was determined by a simplified method using peroxidase as an immune complex antigen. The results correlated well with the hemolytic activity via the classical complement pathway and that via the alternative complement pathway. This simplified method proved to be reliable and useful.
