Fig. 5From: Evidence that phospholipase C is involved in the antitumour action of NSC768313, a new thieno[2,3-b]pyridine derivativeThieno[2,3-b]pyridine has no effect on calcium flux. Calcium flux measured in A431 cells with and without pre-treatment of derivative 3. EGF (400 ng/ml) was added at the time marked by the first vertical arrow, followed by ionomycin (1 µg/ml) as indicated, as a positive controlBack to article page
