Western blot analysis of extracts from PDGF, wortmannin and LY294002 treated NIH/3T3 cells, using Phospho-Akt (Ser473) Antibody (A), Phospho-Akt (Thr308) Antibody (B) or Akt Antibody (C). D is an analysis of Akt kinase activity in PDGF, wortmannin and LY294002 treated NIH/3T3 cells, using the Akt Kinase Assay Kit.

Storage:  Store, as supplied, at –20°C for up to 1 year. Store solutions at -20°C for up to 3 months.

Description:  LY294002 (PI3 Kinase Inhibitor) was shown to act in vivo as a highly selective inhibitor of phosphatidylinositol 3 (PI3) kinase. When used at a concentration of 50 µM, it specifically abolished PI 3-kinase activity (IC₅₀=0.43 µg/ml; 1.40 µM) but did not inhibit other lipid and protein kinases such as PI4 kinase, PKC, MAP kinase or c-Src. LY294002 is soluble in DMSO or ethanol. For use with in vitro or cell-based assays, it may be diluted into aqueous buffers to yield the desired concentrations. For experiments with cultured cells, KangChen recommends treating the cells with LY294002 for one hour prior to, and for the duration of, the stimulation. LY294002 has been shown to block PI3 kinase–dependent Akt phosphory-lation and kinase activity.

Directions for Use: For 10 mM stock, reconstitute 1 mg in 325 µl DMSO. For 50 mM stock, reconstitute 1 mg in 65 µl DMSO. Store aliquots at -20°C. Store solutions at -20°C for up to 3 months.
