Thermo Scientific RIPA Lysis and Extraction Buffer is a high-quality, ready-to-use and fully disclosed formulation of a popular cell lysis reagent for cultured mammalian cells.

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, immunoassays and protein purification. Inhibitors such as Thermo Scientific Halt Protease Inhibitor Cocktail (Part No. 78430) and Halt Phosphatase Inhibitor Cocktail (Part 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.

Frequently asked questions (FAQs)

What are the standard lysis buffers used with mammalian cells for detection of protein expression by immunoprecipitation (IP) or Western blot analysis?

The most commonly used buffer is RIPA Buffer with SDS. We offer RIPA Buffer (Cat. Nos. 89900 and 89901). We also offer the Pierce IP Lysis buffer (Cat. Nos. 87787 and 87788) as well as M-PER (Cat. Nos. 78501, 78503, and 78505).

Does RIPA Lysis and Extraction Buffer (Cat. No. 89900, 89901) contain protease or phosphatase inhibitors?

RIPA Lysis and Extraction Buffer (Cat. No. 89900, 89901) does not contain protease or phosphatase inhibitors. If desired, you may add protease and/or phosphatase inhibitors, such as Halt Protease Inhibitor Cocktail (Cat. No. 78410) and Halt Phosphatase Inhibitor Cocktail (Cat. No. 78420) to the RIPA Lysis and Extraction Buffer to prevent proteolysis and maintain phosphorylation status of proteins. We recommend adding protease and phosphatase inhibitors immediately before use.

Why is it not recommended that I use RIPA buffer for protein A280 measurements with my NanoDrop spectrophotometer?

RIPA buffer produces a particularly strong absorbance signal at the 280 nm wavelength. As a result, it will either over estimate or under estimate protein concentrations and interfere with the protein purity ratio.
Protein samples in RIPA buffer should be quantified via the Pierce Protein 660 or BCA colorimetric assays using a full spectrum NanoDrop model.

Why is there low phosphorylation of the proteins when I use the RIPA Lysis and Extraction Buffer?

Low phosphorylation is usually due to phosphatase activity. We recommend adding a Halt Phosphatase Inhibitor Cocktail to the buffer before use.
Alternatively, the protein is not phosphorylated or phosphorylated at a low level.

What if proteolysis occurs when I use RIPA Lysis and Extraction Buffer?

Proteolysis indicates that no protease inhibitors were added. We recommend adding a Halt Protease Inhibitor Cocktail to the RIPA Lysis and Extraction Buffer before use.

Abstract
Shatavari supplementation in postmenopausal women alters the skeletal muscle proteome and pathways involved in training adaptation.
Authors:O'Leary MF,Jackman SR,Bowtell JL
Journal:European journal of nutrition
PubMed ID:38214710
PURPOSE: Shatavari is an understudied, widely available herbal supplement. It contains steroidal saponins and phytoestrogens. We previously showed that six weeks of shatavari supplementation improved handgrip strength and increased markers of myosin contractile function. Mechanistic insights into shatavari's actions are limited. Therefore, we performed proteomics on vastus lateralis (VL) samples ... More
