[Enzyme multiplied immunoassay technic (EMIT) (author's transl)]

Abstract

In 1960, Yalow and Berson opened the route to radioimmunoassay. Now the technic of radioimmunoassay requires apart from the use of artificial radioisotopes, a compulsory stage of separation of free and linked phases. The author has developed a technic in homogeneous phase "EMIT" which avoids the intermediate stage of separation. He gives here the principle, studies the various parameters of the method, shows the advantages and disadvantages and compares it with other technics and finally mentions future prospects.
