Cells and tumor tissue samples were lysed in RIPA lysis and extraction buffer (cat. 89900, ThermoFisher Scientific) containing Roche complete ULTRA Protease/Phosphatase Inhibitor (cat. 05892791001). Protein concentration was quantified with Pierce BCA Protein Assay Kit (cat. 23225, ThermoFisher Scientific). Isolated proteins were resolved by SDS-PAGE, and Western blot analysis was performed. All primary antibodies were diluted 1:1,000 in 5% w/v nonfat milk. Blots were incubated with primary antibodies overnight at 4°C. GYS1 (cat. ab40810) and ACTIN (cat. ab3280) antibodies were from abcam; HIF-1α antibody was from Cayman (cat. 10006421); HIF-2α antibody was from Novus Biologicals (cat. NB100-122); GAPDH antibody was from Cell Signaling Technology (cat. 2118); PYGL antibody was from Sigma (cat. HPA000962); PYGB antibody was from proteintech (cat. 12075-1-AP). Primary antibodies were detected using horseradish peroxidase–conjugated secondary antibodies from Cell Signaling Technology (cat. 7074) followed by exposure to enhanced chemiluminescence substrate (cat. NEL103001EA, PerkinElmer) or SuperSignal West Femto Maximum Sensitivity Substrate (cat. 34095, ThermoFisher Scientific).

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.
