Ultrastructural demonstration of phosphatases by perfusion fixation followed by perfusion incubation of rat liver

An alternative to previous methods (tissue chopper, frozen sections) for the ultrastructural demonstration of phosphatases is described. The present approach is based on a short vascular perfusion of rat liver with glutaraldehyde through the inferior caval vein, followed by vascular perfusion incubation with a medium containing the enzyme substrates. The… CONTINUE READING
