Lysis
Lysis — The breaking down or destruction of a cell membrane, causing the release of intracellular contents. Used in cell-based peptide research to extract proteins.
What Is Lysis?
Lysis is the disruption of cell membranes to release intracellular contents. In peptide research, lysis is used to extract peptides from cells for analysis, to lyse bacteria for inclusion body recovery, and to measure peptide-induced membrane disruption (lytic activity of AMPs).
Lysis Methods
- Chemical: Detergent lysis (Triton X-100, NP-40) with protease inhibitors
- Mechanical: Sonication, French press, bead beating for bacteria
- Osmotic: Hypotonic buffer causes cell swelling and lysis
- Hemolysis: AMP-induced red blood cell lysis quantified by hemoglobin release at 540 nm
