Summary

A simple modification to the silver staining technique for the demonstration of nucleolar organizer region associated proteins is described. Polyethylene glycol 20 000 is used instead of gelatin as the colloidal developer. This modified technique remains a one stage procedure that is quick and easy to perform. It results in reduced precipitate and less non-specific staining with specimens in which it had been previously difficult to demonstrate these intranuclear silver staining structures.
