Akt1 is involved in cellular survival pathways, by inhibiting apoptotic processes. Akt1 is also able to induce protein synthesis pathways, and is therefore a key signalling protein in the cellular pathways that lead to skeletal muscle hypertrophy, and general tissue growth. Since it can block apoptosis, and thereby promote cell survival, Akt1 has been implicated as a major factor in many types of cancer.

3. What was the protocol?
Treatment of Materials Cells were lysed in 1.5 mls of 1X standard RIPA lysis buffer with protease
inhibitors (PMSF and aprotinin) added. After lysis, samples were spun
down and 4X sample buffer added. About 35 ul of the lysed cells was
separated by SDS-PAGE at 10% and then transferred and blotted
Gel Electrophoresis 10% polyacrylamide gel, constant voltage 120V, 80 min. 50 ug per lane.
Transfer Nitrocellulose membrane
Blocking 1X TBST with 10% skimmed milk powder for 45 minutes.
Primary Antibody Application 1:1000 primary antibody was added to the solution of 1X TBST with 2.5%
skimmed milk powder, 4˚C for overnight.
Secondary Antibody Application Secondary antibody (anti-rabbit HRP) was added to the solution of 1X TBST
with 2.5% skimmed milk powder with 1:7500 dilution ratio, for 1.5 hours.
Visualisation ECL kit

4. What was the protocol?
Gel electrophoresis information: 10 % polyacrylamide gel, constant voltage 90 V for 90 min.
Transfer information: nitrocellulose membrane, 1 piece of gel (semi-dry transfer) at 260 mA for 3 hours

5. What were the results?

6. “The results demonstrate that the pS473 Akt can specifically recognize activated Akt in mouse
samples. Most likely it will recognize human Akt. Antibody appears quite good.”
Testing results were provided independently by Professor Shairaz Baksh at the University
of Alberta. They stated that:
