A method for a radioimmunoassay using microtiter plates allowing simultaneous determination of antibodies to two non cross-reactive antigens

Abstract

A triple isotype (²²Na,¹³¹I,¹²⁵I) radioimmunoassay method employing microtiter plates and specially designed disposable paperware has been devised. This procedure allows the determination of antibodies to two non cross-reactive antigens simultaneously on large numbers of samples.
