Heterogenous distribution of potassium and phosphorus in Acanthamoeba castellanii.

Using x-ray microanalysis technique the distribution of potassium, phosphorus and sulphur was analysed in Acanthamoeba castellanii cells. Distribution of potassium was nonuniform; the high level of the element was observed in the cortex region of these cells. Distribution of phosphorus was shown to be similar to that of potassium, whereas sulphur was rather uniformly distributed.
