Thermo Scientific™ RIPA Lysis and Extraction Buffer

Features of RIPA Buffer:

• Convenient—ready-to-use solution; no need to assemble and prepared components yourself
• Flexible—compatible with many applications, including reporter assays, protein assays, immunoassays and protein purification
• Versatile—enables extraction of cytoplasmic, membrane and nuclear proteins
• Disclosed formulation—contains no proprietary components, providing users with complete control and knowledge of possible compatibility issues

This RIPA buffer effectively lyses and extracts protein from cultured mammalian cells, including plated cells and pelleted suspension cells. The popular reagent enables the extraction of membrane, nuclear and cytoplasmic proteins and is compatible with many applications, including reporter assays, the Thermo Scientific BCA Protein Assay (Cat. No. 23225), immunoassays and protein purification. Inhibitors such as Thermo Scientific Halt Protease Inhibitor Cocktail (Cat. No. 78420) and Halt Phosphatase Inhibitor Cocktail (Cat. No. 78420) are also compatible with this RIPA buffer formulation and can be added before use to prevent proteolysis and maintain protein phosphorylation.

RIPA buffer derives its name from the original application for which it was developed: the radio-immunoprecipitation assay. While this isotopic assay method is rarely performed in laboratories today, the acronym for this lysis buffer formulation has endured in common use. RIPA cell lysis reagent is highly effective for protein extraction from a variety of cell types because it contains three non-ionic and ionic detergents. One disadvantage of this detergent formulation is its relative incompatibility with certain downstream applications compared to other lysis reagents.
