Abstract
The paper describes four autoradiographic techniques which can be recommended, not without restrictions, for the study of the cellular and subcellular hormone or drug distribution in tissues. In all of the techniques desiccated slides are used which are precoated with photographic emulsion. The techniques are (I) Dry-mounting of freeze-dried sections on emulsion precoated slides; (II) Thaw-mounting of frozen sections on emulsion precoated slides; (III) Smear-mounting on emulsion precoated slides; and (IV) Touch-mounting on emulsion precoated slides. The techniques are designed to avoid or minimize translocation of the labelled molecules during preparation and during the application to photographic emulsion. Cited examples of application of these techniques demonstrate their utility in hormone research.
