The Thermo Scientific Mem-PER Plus Membrane Protein Extraction Kit enables small-scale solubilization and enrichment of integral membrane proteins and membrane-associated proteins in a simple reagent-based procedure.
Features of the Mem-PER Plus Kit:
• Extraction and isolation—produces minimal cross-contamination (typically less than 10%) of cytosolic protein into the membrane protein fraction
• Cells or tissues—effective for extraction from cultured mammalian cells and mammalian tissues
• Downstream compatibility—analyze membrane protein extracts by SDS-PAGE, western blotting, immunoprecipitation and protein assays
• Fast and simple—isolation of membrane proteins in approximately one hour
• No special equipment required—only a benchtop microcentrifuge, tubes, homogenizers, and pipettors are needed
The Mem-PER Plus Kit effectively isolates membrane proteins from cultured cells and tissues using a simple benchtop microcentrifuge procedure. Integral membrane proteins having one or two membrane-spanning domains are effectively solubilized and isolated from cytosolic proteins. The kit makes possible the extraction and selective enrichment of integral and attached membrane proteins from cultured mammalian cells, as well as from hard and soft mammalian tissues. The Mem-PER Plus Kit has many advantages compared to our original Mem-PER Kit. The protocol is simpler, and the fractions are directly compatible with many downstream applications such as SDS-PAGE, Western Blotting, BCA, immunoprecipitation, and amine-reactive protein labeling techniques.
Includes:
Kit contains a cell wash solution, permeabilization buffer, and solubilization buffer.
Traditional methods for isolation of membrane protein are tedious and time-consuming, and they require gradient separation and expensive ultracentrifugation equipment. The Mem-PER Plus Membrane Protein Extraction Kit is for the enrichment of integral membrane proteins and membrane associated proteins from cultured mammalian cells or tissue using a mild detergent-based selective extraction protocol. The use of selective detergent extraction eliminates the hassle of phase separation based on hydrophobicity, allowing better reproducibility and higher throughput.
The cells are first permeabilized with a mild detergent, allowing the release of soluble cytosolic proteins, after which a second detergent solubilizes membrane proteins. Extraction efficiencies and yields will vary depending on cell type as well as the number of times the integral membrane protein spans the lipid bilayer. Membrane proteins with one or two transmembrane domains are typically extracted with an efficiency of up to 90%. Cross-contamination of cytosolic proteins into the membrane fraction is usually less than 10%.
