Tannic acid-metal salt sequences for light and electron microscopic localization of complex carbohydrates.


Use of tannic acid (TA), in sequence with ferric chloride, uranyl acetate or gold chloride resulted in staining of selective but sometimes different sites in paraffin sections. TA-uranyl acetate of TA-ferric chloride stained sites rich in complex carbohydrates, wherease TA-gold chloride stained the collagen of various connective tissues different shades of… (More)
