The K-LISA™ Akt Activity Kit is a rapid, sensitive, ELISA-based activity assay suitable for measuring the kinase activity of purified or partially purified Akt preparations, in vitro Akt inhibitor screening, and for assessing the regulation of Akt in cell signaling. The assay utilizes a biotinylated peptide substrate (GRPRTSSFAEG) that is phosphorylated on the second serine by Akt1, Akt2, Akt3, SGK (Serum Glucocorticoid Kinase), and MSK1. Biotinylated Akt substrate and sample containing Akt are incubated in the presence of ATP in wells of a streptavidin-coated 96-well plate, which allows for phosphorylation and substrate capture in a single step.

 Near-confluent MCF-7 cells were stimulated with IGF-1 (100 ng/ml) or IGF-1 (100 ng/ml) and 17β-estradiol (500 nM) for 30 min at 37°C in a CO<sub>2</sub> incubator. For inhibition of Akt, cells were first pre-incubated at 37°C in a CO<sub>2</sub> incubator for 15 min in the presence of cell-permeable Akt Inhibitor II (Cat. No. 124008) followed by stimulation with IGF-1 (100 ng/ml) for 30 min at 37°C. Cell lysates were prepared using 0.5 ml PhosphoSafe™ Extraction Buffer per 10 cm cell culture dish, per the standard protocol. Cell lysates were either used immediately or stored at -70°C until use. Equal amounts of total protein (1.5 mg) were immunoprecipitated and the activity was determined as outlined in protocol B under the Detailed Protocol section. |
