Cells were pelleted and lysed with M-PER (Thermo Scientific Pierce) supplemented with a cocktail of protease and phosphatase inhibitors (Sigma-Aldrich). Protein lysates were collected by centrifugation at 13,000 RPM for 10 min at 4°C and pre-cleared by incubation with Thermo Protein A/G Dynabeads (Thermo Scientific Pierce) for 3 hours at 4°C on a rotator. Pre-cleared protein lysates were quantified with the BCA Protein Assay Kit (Thermo Scientific Pierce), and 2 mg/ml lysates were prepared. We used anti-Gα12/13, anti-LARG and anti-RhoA antibodies for pull-down and immunoblotting at the recommended dilutions. Cell lysates were separated by SDS-PAGE and transferred onto nitrocellulose membranes. Blots were scanned digitally using the ChemiDoc™ touch imaging system (Bio-Rad).

Whole cell lysates were prepared by using M-PER as mentioned above, and were pre-cleared by incubation with Thermo Protein A/G Dynabeads (Thermo Scientific Pierce) for 3 hours at 4°C on a rotator. Pre-cleared protein lysates were quantified with the BCA Protein Assay Kit, and 2 mg/ml lysates were prepared. We used anti-NIS, anti-LARG and anti-RhoA antibodies for pull-down and immunoblotting at the recommended dilutions. Cell lysates were separated by SDS-PAGE and transferred onto nitrocellulose membranes. Blots were scanned digitally using the GE Amersham Imager 600 (GE Healthcare Life Science).

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.
