Permeabilization
Permeabilization — The process of making cell membranes permeable using detergents or peptides to allow access to intracellular targets for staining or analysis.
What Is Permeabilization?
Permeabilization is the creation of pores or openings in cell membranes to allow entry of molecules. In peptide research, permeabilization describes: (1) the membrane-disrupting mechanism of AMPs, (2) fixation/permeabilization for intracellular immunostaining, and (3) transient permeabilization for peptide delivery.
Methods
- AMP mechanism: Pore formation or carpet model disruption of bacterial membranes
- Staining: 0.1% Triton X-100 or 0.5% saponin to access intracellular targets for IF
- Electroporation: Electrical pulses create transient pores for peptide delivery to cells
