Western Blot Analysis of Foxo and Akt

Check if the same lab product or an alternative is used in the 5 most similar protocols
Cells were washed in PBS and then lysed. The protein concentration of each cell lysate was determined and equated. Prepared samples were boiled in sample buffer at 100 °C for 5 minutes. Samples were loaded in SDS-PAGE gel and the gel ran at 140–160 V. After electrophoresis proteins were transferred to the PVDF membrane. Membranes were blocked for 1.5 h at room temperature using blocking buffer (5% nonfat dry milk) and incubated with primary antibodies for 1 h at room temperature or overnight at +4 °C. Then membranes were incubated with HRP-conjugated secondary antibodies diluted in blocking buffer for 1h at room temperature. As primary antibodies, we used antibodies to Foxo1 #2880, Foxo3a #2497, phospho-Foxo3a #9466, Akt #9272, phospho-Akt #4060 (Cell Signalling).

Western Blot Analysis of Cellular Proteins

Check if the same lab product or an alternative is used in the 5 most similar protocols
Cells were lysed with lysis buffer (Cell Signaling Technology, Danvers, MA, USA), and equal amounts of protein were resolved by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) on 8–12% gels and transferred to nitrocellulose membranes. The membranes were blocked by incubating with 5% non-fat dry milk in PBS containing 0.2% Tween-20 (PBST) for 1 h, and then incubated with primary antibodies overnight at 4 °C. After three washes with PBST, blots were incubated with horseradish peroxidase (HRP)-conjugated secondary antibodies against mouse (#A120-101P) or rabbit (#A90-116P) (Bethyl Laboratories, Inc., Montgomery, TX, USA) for 1 h at room temperature. Protein bands were detected using enhanced chemiluminescence (ECL) reagents (Amersham Pharmacia Biotechnology, Amersham, UK) and X ray film (AGFA, Mortsel, Belgium). Primary antibodies against ARPP19 (#MBS9609642) were obtained from MyBioSource (San Diego, CA, USA); phospho-AKT (#4060) and AKT (#4691) were obtained from Cell Signaling Technology; c-Myc (#sc-764), cyclin D1 (#sc-753), E-cadherin (#sc-8426), and β-actin (#sc-47778) were purchased from Santa Cruz Biotechnology (Santa Cruz, CA, USA).

TDI (toluene-2, 4-diisocyanate, ≥ 98.0%), acetone, and methacholine were obtained from Sigma-Aldrich (Shanghai, China). The vehicle that TDI was dissolved in was a mixture of acetone and olive oil (AOO): the ratio of acetone to olive oil was 2:3 for sensitization, and 1:4 for challenge. FPS-ZM1 (RAGE inhibitor), JNJ-26482585 (HDAC inhibitor), romidepsin (HDAC inhibitor), and MK2206 (AKT inhibitor) were purchased from Selleck (SelleckChem, Shanghai, China).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
