Thermo Scientific M-PER Mammalian Protein Extraction Reagent is designed to provide highly efficient total soluble protein extraction from cultured mammalian cells.

Features of M-PER Mammalian Protein Extraction Reagent:

Gentle—mild detergent lysis, yielding extracts that are immediately compatible with coomassie (Bradford) and BCA protein assays or SDS-PAGE
Compatible—extracts soluble proteins in nondenatured state, enabling direct use in immunoprecipitation and other affinity purification procedures
Amine-free and dialyzable—formulation ensures compatibility with subsequent assay systems
Convenient—lyse adherent cells directly in plate or after scraping and washing in suspension
Non-denaturing—maintain activity of luciferase, beta-galactosidase, CAT and other reporter genes as well or better than other suppliers' products and freeze/thaw methods

Product Details

The complete cell lysis reagent contains a mild, nondenaturing detergent that dissolves cell membranes to extract and solubilize total protein from most cellular compartments. Extraction is accomplished in only 5 minutes and requires little or no additional mechanical disruption. M-PER reagent is formulated for minimal interference with downstream biological applications. The reagent has been validated for use with several cell lines, including primary, suspension and adherent cell types; the resulting cell lysates are compatible with many downstream assays including immunoassays, enzyme assays and a variety of common reporter assays.

Cellular protein extraction—cell lysis to release the proteins of interest—is a key first step in many proteomics analysis procedures. M-PER reagent is designed to efficiently extract soluble protein from a variety of cell types, including primary cells and cells grown in suspension or adherent culture conditions. Performance of M-PER reagent was evaluated for yields of both total protein and specific target proteins from the various cellular compartments. Additionally, because M-PER reagent is formulated with dialyzable components that are devoid of primary amines, it is more compatible with certain downstream applications, such as luciferase, beta-galactosidase, and CAT assays, than other protein extraction methods.

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).

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.
