Bright-field image of human iiver parenchymal cells, where peroxisomes are stained dark brown with DAB by their catalase activity at pH 10.5, and postosmicated. Cell nuclei are counterstained with lig...

Peroxisomes in human parenchymal liver cell, contrasted for catalase activity. Reaction product typically differs between individual organelles. Several mitochondria are seen, as well as many dark gl...

Human duodenal epithelium, peroxisomes contrasted with DAB by their catalase activity at pH 10.5, postosmicated, embedded in epon resin, and visualized using electron microscopy. Image shows two types...

Low magnification electron micrograph showing peroxisomes in several parenchymal cells in human liver, contrasted by catalase activity with DAB. A few organelles show a heterogeneous content: they are...

Human duodenal epithelium. Peroxisomes are stained with DAB at pH 10.5 by their catalase activity and postosmicated. 0.5 µm plastic section were visualized using electron microscopy at low magnificat...

Image of normal human iiver parenchymal cells, where peroxisomes are stained brown with DAB by their catalase activity at pH 10.5. No counterstain was used. Prefixation was carried out in buffered for...

Human duodenal epithelium, at the level of the crypt. Fixation was carried out inbuffered formal-calcium. Peroxisomes are stained with DAB by their catalase activity at pH 10.5, postosmicated and embe...
