Wortmannin #9951

Directions for Use

For 1 mM stock, dissolve 1 mg in 2.32 ml DMSO. For experiments with cultured cells, CST recommends treating with wortmannin at concentrations between 0.2 µm and 1 µm, for one hour prior to, and for the duration of, the stimulation. See MSDS for further information.

Western Blotting

Western Blotting

Western blot analysis of extracts from untreated, wortmannin and/or LY294002 treated Jurkat cells, using Phospho-Akt (Ser473) Antibody #9271 (A), Phospho-Akt (Thr308) Antibody #9275 (B), Akt Antibody #9272 (C) and Phospho-GSK-3alpha/beta (Ser21/9) Antibody #9331 (D).

Background

Wortmannin is a very potent, specific and direct inhibitor of PI3 kinase, originally derived from fungus (1,2). The inhibition is irreversible and noncompetitive. Wortmannin does not inhibit PI4 kinase, protein kinase C or protein tyrosine kinase (3).
