title: Cystic fibrosis: the effect of medium from cultured cystic fibrosis fibroblasts on ATPase activity.
abstract: Culture medium from fibroblasts of cystic fibrosis patients and controls was examined for the ability to inhibit (calcium plus magnesium)-activated ATPase and (sodium plus potassium)-activated ATPase. The ATPase systems used were both a solubilised preparation from dog-fish and a membrane associated preparation from human erythrocyes. Contrary to other reports the medium from cystic fibrosis fibroblasts did not inhibit ATPase activity.
