A Modified Feulgen Technic for Small and Diffuse Chromatin Elements

Abstract
A revised technic is proposed which differs essentially from the standard procedure only in the preparation of the staining solution and of the sulphurous acid bath, which are made by direct charging with SO2 gas instead of HC1 and the sulphites ordinarily used. Tests on smear preparations of small amoebae, oocyte prophases of a parasitic wasp, and yeasts revealed Feulgen-positive results not usually obtained by the conventional method.
