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...

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...

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...

Light micrograph of a longitudinal section of the epididymis. The lining of the duct consists of pseudostratified epithelial cells, which have prominent microvilli on their free surface extending in...

Mouse tracheal epithelia cells (MTEC) were grown at air-liquid interface to induce differentiation, centriole amplification and ciliogenesis. Cells were fixed using ice-cold methanol for 10 min. Sampl...

A figure from Chapter 13 (Cilia and Flagella) of 'The Cell' by Don W. Fawcett M.D. The microtubules of the axoneme are adequately preserved by routine fixation for electron microscopy of thin sections...
