Does diaminobenzidine demonstrate prostaglandin synthetase? A study on polyunsaturated fatty acid-induced DAB oxidation in sheep vesicular glands and rabbit kidney medulla.


A method histochemical localization of prostaglandin synthetase using DAB, potassium cyanide and polyunsaturated fatty acid has been revised. The arachidonic acid-induced DAB oxidation observed in the secretory epithelium of sheep vesicular glands and in collecting tubules as well as intersititial cells of rabbit kidney medulla was found to be insensitive… (More)
