electron microscopic dopa reaction of glutathione-treated cells shows a predominant localization of tyrosinase activity in the golgi-associated endoplasmic reticulum-lysosome and coated vesicles , but not in premelanosomes , in contrast to their dispersed distribution in all melanogenic organelles in the theophylline-treated control , suggesting a lack of tyrosinase translocation .
