Pierce radioimmunoprecipitation assay lysis buffer

Manufactured by Thermo Fisher Scientific
Sourced in United States

The Pierce radioimmunoprecipitation assay (RIPA) lysis buffer is a buffer solution used to extract and solubilize proteins from cells or tissues for further analysis. It contains a combination of detergents, salts, and buffers that aid in the disruption of cell membranes and the release of intracellular proteins.

Protein lysates were prepared from cell pellets following direct isolation or cell sorting using Pierce radioimmunoprecipitation assay lysis buffer (Thermo Fisher Scientific; 89900) and standard methods. Lysates were run on 10% Mini PROTEAN TGX precast gels (Bio-Rad Laboratories) and transferred onto 0.2-µm nitrocellulose membranes (Bio-Rad Laboratories; 162-0146). Membranes were blocked in 5% milk and immunoblotted with primary antibody to GIMAP5 (MAC421; Wong et al., 2010 (link); courtesy of Dr. Butcher) overnight at 4°C or with GAPDH (Invitrogen; AM4300) for 1 h at room temperature. Secondary antibodies used were ECL anti-rat IgG HRP-linked whole antibody (GE Healthcare; NA935) and ECL peroxidase-labeled anti-mouse antibody (GE Healthcare; NA931), respectively. Immunostaining was detected using Amersham ECL and ECL Prime Western Blotting detection reagents (GE Healthcare).

Western Blot Analysis of Akt and ERK

Protein samples were collected after UDCA treatment. Treated cells were lysed with Pierce radioimmunoprecipitation assay lysis buffer (Thermo Scientific, Waltham, MA, USA) containing protease inhibitor. Lysates were then processed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Proteins were quantified using the Bradford assay (Thermo Scientific), resolved on a 10% Bis-Tris gel, and transferred to a nitrocellulose membrane. The membrane was then blocked for 1 h at room temperature with 5% bovine serum albumin and washed with 1X phosphate-buffered saline-Tween-20 buffer, before being incubated with anti-Akt and -ERK primary antibodies (Cell Signaling Technology, Danvers, MA, USA) for 24 h at 4°C. Immunoreactive bands were detected using anti-immunoglobulin G secondary antibodies and chemiluminescence reagents (Thermo Scientific). Immunoblots were visualized using X-ray film.

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.
