Thermo Scientific M-PER哺乳动物蛋白质抽提试剂用于从培养的哺乳动物细胞中高效抽提总可溶性蛋白。

M-PER哺乳动物蛋白抽提试剂的特点：

• 作用温和— 温和的除垢剂裂解，产生的抽提物直接与考马斯(Bradford)和BCA蛋白定量分析试剂或SDS-PAGE兼容
• 兼容性强— 抽提的可溶性蛋白处于非变性状态，可直接用于免疫沉淀反应和其他亲和纯化过程
• 不含胺基并且可透析— 确保其与随后的分析系统兼容
• 方便— 贴壁细胞直接在板上裂解或者在剥离和洗涤后悬浮于溶液中
• 非变性— 维持荧光素酶、β-半乳糖苷酶、CAT和其他报告基因的活性，与其他供应商的产品和冷冻/解冻方法一样好或更出色

这款完整的细胞裂解试剂是一种非变性除垢剂配方，可在短短5分钟内溶解细胞膜并抽提总可溶性细胞蛋白。M-PER试剂很少或根本不需要机械破碎，并且相比冷冻/解冻循环方法和超声波破碎方法可以获得更多的蛋白。这种哺乳动物细胞裂解试剂是如此有效，不需要从培养皿上剥离贴壁细胞，可以简单而直接地在生长细胞的24孔和96孔板上进行裂解和分析。最终无论是贴壁细胞还是悬浮细胞的裂解产物与很多下游分析都兼容，包括免疫分析、酶分析和各种常见的报告基因分析。

在任何蛋白质组学分析过程中，蛋白质抽提通常都是关键的第一步，首先细胞必须裂解，以便打开细胞并释放出感兴趣的蛋白质。常用的几种物理裂解细胞方法包括机械破坏、液体均质化、超声波裂解、冷冻/解冻循环和手工研磨。

常见问题解答 (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).

Is the M-PER Mammalian Protein Extraction Reagent (Cat. No. 78501, 78503, 78505) compatible with Mass spectrometry (MS)?

As any other lysis reagent, M-PER has detergent and salts in its composition, and both type of components need to be removed before the MS analysis, as they will interfere with the analysis. According to the workflow used in the MS analysis, those might be removed before the MS analysis. We recommend removing detergents at the protein level. Both detergent and salts can be removed by dialysis.

Can you provide the shelf-life for the M-PER Mammalian Protein Extraction Reagent?

The M-PER Mammalian Protein Extraction Reagent is covered under our general 1-year warranty and is guaranteed to be fully functional for 12 months from the date of shipment, if stored as recommended (room temperature). Please see section 8.1 of our Terms & Conditions of Sale (https://www.thermofisher.com/content/dam/LifeTech/Documents/PDFs/Terms-and-Conditions-of-Sale.pdf) for more details.

Will M-PER Mammalian Protein Extraction Reagent extract membrane or cytoskeletal proteins?

M-PER Mammalian Protein Extraction Reagent can extract some membrane or cytoskeletal proteins, but the extraction efficiency is not consistent. The reagent was not intended to specifically extract these proteins. We recommend using Mem-PER Plus Membrane Protein Extraction Kit (Cat. No. 89842) for membrane protein extraction or Subcellular Protein Fractionation Kit for Cultured Cells (Cat. No. 78840) for compartmental extraction.

When using the M-PER Mammalian Protein Extraction Reagent, is it necessary to remove cells from the plate? Should I use scraping or trypsinization to remove the cells from the plate?

M-PER reagent works very well with adherent and suspension cells, making it unnecessary to separate the cells from the plate. However, if cell removal is desired, scraping is the recommended procedure for removing cells from the plate. Trypsinization is not recommended as the free trypsin left behind in the lysis solution can damage lysed proteins.
