[Heterologous and homologous radioimmunoassays for human prolactin. 1. Development and critical evaluation of the method].

Based on the production of a high specific antibody against ovine prolactin a heterologous prolactin RIA (self proposed method) is introduced. From this work both a homologous and a heterologous system have been developed and used for the PRL-RIA kit production. Substances necessary for setting up the kits, their investigations and applications are described. Statistical considerations about precision, sensitivity, specificity and accuracy show the validity of these heterologous PRL-systems.
