Abstract
THE fact that a nearly colourless solution of 2 : 3 : 5 triphenyl tetrazolium chloride (tetrazolium salt) is reduced to a red formazan in contact with living tissue has been recognized for some time. This has been used in testing for viability and also for staining tissues; but detailed descriptions of the colour distribution within tissues are lacking. Since the red colour is due to reduction of the agent, the colour distribution should offer some evidence as to the intracellular distribution of reducing groups.
