[Developments in immunofluorescence (author's transl)].

This report presents a review of recent developments in immunofluorescence and their resultant applications. After a short introduction to the basic principles of immunofluorescence, this study deals with newer developments in utilizable fluorochromes, new methods in the production of antisera and fluorochrome-labelled conjugates and recent improvements in the optical system. In particular, the necessity of suitable characterization and examination in regard to the quality of the conjugates is described in detail. A separate chapter has been devoted to the rapidly-developing quantitative immunofluorescence technique and its application.
