Fixed cells and tissues pretreated with 4-hydroxynonenal were used as models for the histochemical demonstration of protein bound aldehydic groups. The aldehydes were stained with both a modification of the 2,4-dinitrophenylhydrazine method (2,4-DNPH) and the optimized staining using 3-hydroxy-2-naphthoic acid
