Detergent used to plasma membrane
WebPermeabilization provides access to intracellular or intraorganellar antigens. Two general types of reagents are commonly used: organic solvents, such as methanol and acetone, and detergents such as saponin, Triton X-100 and Tween-20. The organic solvents dissolve lipids from cell membranes making them permeable to antibodies. WebSep 20, 2024 · In this work, we propose a fast, detergent-based protocol for the purification of membrane proteins from murine and human cells. This protocol is based on three steps: cell washing to remove cell culture medium proteins, cells permeabilization using digitonin to remove the intracellular components, and cell membranes disruption using Triton X ...
