Figure 5From: Inducible expression of catalytically active type 1 serine/threonine protein phosphatase in a human carcinoma cell lineDephosphorylation of phosphorylase a by anti-hemagglutinin immunoprecipitates from uninduced (Control) and induced (Doxycycline) LLW02 cells. Activity was assayed by the release of [32P] H3PO4 from radiolabeled phosphorylase a (1–2 × 105 cpm/nmol). 1 unit of activity releases 1 nmol of phosphate/min at 30°C.Back to article page
