CE0050 Sigma

CelLytic MEM Protein Extraction Kit




The kit offers a fast and convenient method to isolate hydrophobic and raft microdomain associated proteins from cells. The method is based on phase separation and does not require cell membrane isolation. The separated proteins can be used for further experiments such as SDS-PAGE, Western blotting, dot blotting, and immunoprecipitation. The kit has been tested on, but not limited to, HeLa, HEK-293, NIH 3T3, COS and CHO cell lines.

General description

Membrane proteins make up around 20-30% of an organism′s genome and serve as cellular gatekeepers, regulators, and sensors. They have diverse cellular functions, such as shielding the cell from external toxins, being the starting point of intracellular signaling cascades, and retaining critical ion concentrations.


Sufficient reagents supplied for 80 tests.
