[In vitro calcium binding by isolated brush border vesicles of rat jejunum and ileum].
A new procedure for isolation of the Rat jejunum and ileum brush border vesicles is described. Several calcium transport conditions have been established. A previous incubation with ATP induces an increased calcium binding. The role of a magnesium ATPase is discussed.
