Thermo Scientific RIPA Lysis and Extraction Bufferは培養哺乳類細胞用の高品質ですぐに使用可能な一般的な細胞溶解試薬で、組成が完全に公開されています。

RIPAバッファーの特長:

便利—すぐに使用可能な溶液;自身で成分を調製す必要なし
柔軟—レポーターアッセイ、タンパク質アッセイ、イムノアッセイ、およびタンパク質精製など、多くのアプリケーションに適合
汎用—細胞質、膜、および核のタンパク質を抽出可能
公開されている組成—独自の成分を含有していないため、ユーザーは起こり得る適合性の問題を完全にコントロールし知ることが可能

このRIPAバッファーは、プレートで培養した細胞やペレット化した懸濁細胞などの培養哺乳類細胞を効果的に溶解し、タンパク質を抽出します。この一般的な試薬は、膜、核、および細胞質のタンパク質を抽出し、レポーターアッセイ、Thermo Scientific BCA Protein Assay、イムノアッセイ、およびタンパク質精製など、多くのアプリケーションに適合します。Thermo Scientific Halt Protease Inhibitor Cocktail(製品番号78430)やHalt Phosphatase Inhibitor Cocktail(製品番号78420)などの阻害剤もRIPAバッファー組成に適合し、使用前に添加することでタンパク質分解を防ぎ、タンパク質のリン酸化を維持できます。

RIPAバッファーの名前は、開発目的であったオリジナルアプリケーション、すなわち放射性免疫沈降法(radio-immunoprecipitation assay)に由来します。今日、この同位体アッセイ法がラボで実施されることはほとんどありませんが、この溶解バッファー製剤の頭字語は広く使用され続けています。RIPA細胞溶解試薬は3種類の非イオン性およびイオン性の界面活性剤を含有しているため、さまざまな細胞タイプからタンパク質を効果的に抽出します。この界面活性剤の短所は、他の溶解試薬と比較して、特定のダウンストリームアプリケーションとの適合性が相対的に乏しい点です。

よくあるご質問(FAQ)

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
