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

nThe complete cell lysis reagent is a nondenaturing detergent formulation that dissolves cell membranes and extracts total soluble cellular protein in only 5 minutes. M-PER Reagent requires little or no mechanical disruption and yields more protein than freeze/thaw cycles and sonication. This mammalian cell lysis reagent is so efficient that adherent cells do not need to be scraped from the culture dish, enabling easy and direct lysis and analysis of cells grown in 24-well and 96-well plates. Resulting cell lysates from either adherent or suspension cells are compatible with many downstream assays including immunoassays, enzyme assays and a variety of common reporter assays. Highlights:

- 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 luciferase, ß-galactosidase, CAT and other reporter gene activities as well or better than other suppliers’ products and freeze/thaw methods
