Figure 1. Western blot of AKT1 and pAKT1 in HCT116 parental, AKT2−/−, and AKT1−/− cells serum starved overnight and treated (or not treated) with insulin (20 μg/ml) for 30 min. ERK immunoblotting showed equivalent loading. From [1].

Rabbit monoclonal IgG

Company: Cell Signaling

Antibody: Phospho-Akt1 (Ser473)

Catalog number: 9018

Summary: Rabbit monoclonal IgG a synthetic phosphopeptide corresponding to residues surrounding Ser473 of human Akt1 protein. Reacts with human, mouse and rat. Suitable for western blot, immunoprecipitation, immunofluorescence/immunocytochemistry, and flow cytometry.

Western blot

HCT116 parental, AKT2−/−, and AKT1−/− cells. Cells were lysed in radioimmunoprecipitation assay (RIPA) buffer (50 mM Tris-HCl (pH 7.4), 150 mM NaCl, 1% NP-40, 0.5% sodium deoxycholate, and 0.1% sodium dodecyl sulfate), supplemented with protease inhibitor and phosphatase inhibitor cocktails (Pierce Biotechnology, Rockford, IL).
