The actual size of p-Akt is 60 Kda. Why it is not detected in Vero and HeLa cells? I am using both protease and phosphatase inhibitors in the lysates. Has anyone experienced same problem?
have you tried probing for normal AKT? Is your antibody pan-AKT? as there are multiple AKT isomers. have you already optimized the antibody and included a positive control on your blot to ensure it has worked?
