El reactivo de extracción de proteínas de mamíferos Thermo Scientific M-PER se ha diseñado para proporcionar una extracción de proteínas solubles totales de alta eficacia de células de mamíferos cultivadas.

Características del reactivo de extracción de proteínas de mamíferos M-PER:

Suave: lisis suave mediante detergente que produce unos extractos compatibles de inmediato con ensayos de proteínas con ácido bicinconínico (BCA) y Coomassie (Bradford) o electroforesis en gel de poliacrilamida con dodecilsulfato sódico (SDS-PAGE).
Compatible: extrae proteínas solubles en estado no desnaturalizado, lo que permite su uso directo en inmunoprecipitación y otros procedimientos de purificación por afinidad.
Dializable y sin aminas: la formulación garantiza la compatibilidad con sistemas de ensayo posteriores.
Práctico: lise células adherentes directamente en la placa o después del raspado y el lavado en suspensión.
No desnaturalizante: mantenga la actividad de la luciferasa, beta-galactosidasa, cloranfenicol acetiltransferasa (ACT) y otros genes indicadores con un rendimiento igual o superior a métodos de congelación/descongelación y productos de otros proveedores.

Detalles del producto

El reactivo de lisis celular completa contiene un detergente no desnaturalizante suave que disuelve las membranas celulares para extraer y solubilizar las proteínas totales de la mayoría de compartimentos celulares. La extracción se realiza en solo 5 minutos y requiere poca o ninguna interrupción mecánica adicional. El reactivo M-PER se ha formulado para una interferencia mínima con aplicaciones biológicas posteriores. El reactivo se ha validado para su uso con varias líneas de células, incluidas células primarias, adherentes y en suspensión. Los lisados celulares resultantes son compatibles con muchos ensayos posteriores, como los inmunoensayos, los ensayos con enzimas y una serie de ensayos con indicadores comunes.

La extracción de proteínas celulares (lisis celular para liberar las proteínas de interés) es un primer paso fundamental en la mayoría de procedimientos de análisis de proteómica. El reactivo M-PER se ha diseñado para extraer de forma eficaz las proteínas solubles de distintos tipos de células, incluidas las células primarias y las células que crecen en cultivos adherentes o de suspensión. El reactivo M-PER se ha evaluado en función de la producción de proteínas totales y proteínas diana específicas de distintos compartimentos celulares. Además, dado que el reactivo M-PER se formula con componentes dializables sin aminas primarias, es más compatible con determinadas aplicaciones posteriores, como los ensayos con CAT, luciferasa y beta-galactosidasa, que otros métodos de extracción de proteínas.

Preguntas frecuentes

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.
