说明

一般說明

A potent, ATP-competitive, and specific inhibitor of casein kinase II (IC₅₀ = 6 µM). Reported to inhibit insulin-stimulated nuclear and cytosolic p70S6 kinase in CHO cells. Accentuates premature termination of transcription. Has been used to inhibit RNA polymerase II transcription which may be dependent on casein kinase II. Inhibits germinal vesicle breakdown in bovine oocytes. Induces G₁/S cell cycle arrest.

Accentuates premature termination of transcription close to the promoter. Useful for isolation of RNA sequences near promoter sites that are responsible for mRNA formation. Useful for reversible superinduction of human fibroblast cultures. Potent, ATP-competivie and specific inhibitor of casein kinase II (IC₅₀ = 6 µM). Has been used to inhibit RNA polymerase II transcription, which may be dependent on casein kinase II. Inhibits germinal vesicle breakdown in bovine oocytes.
