[Electron microscope localization of thiamine pyrophosphatase and nucleoside diphosphatase in lymphocytes].
In ductus thoracicus lymphocytes of the rat the localization of specific phosphatases was studied by means of ultrahistochemistry. Thiaminepyrophosphatase was found in the outer lamellae of the Golgi-field as well as in lysosomes, whereas nucleosiddiphosphatases could be localized on the plasma membrane at low pH. These findings are correlated with the phaenotype of B- and T-lymphocytes. Their functional significance is discussed.
