Cell Disruptor: The "Key" to Unlocking the Microcosm

What is Cell Lysis?

Cell disruption refers to the process of breaking down cell walls or cell membranes through physical, chemical, or biological methods to release intracellular contents. This technology is a fundamental step in modern biotechnology, pharmaceutical research and development, and the food industry, acting as a "key" that opens the door to the microscopic world, allowing us to obtain valuable substances such as proteins, enzymes, and DNA from within the cells.

Cell Disruption Techniques Classification

Mechanical crushing method

These methods directly disrupt cell structures through physical force:

High-pressure homogenizer: Cell suspensions pass through narrow gaps under extremely high pressure (up to 1500bar), causing an instantaneous pressure drop that generates cavitation effects and shear forces, leading to cell rupture.

Zirconium Grinding Mill: Cells and micro-sized grinding beads (such as glass beads, ceramic beads) collide with each other under high-speed stirring,破碎 cells through the grinding action.

Ultrasonic Crusher: Utilizes high-frequency sound waves (typically 20-50 kHz) to create cavitation bubbles, which, upon bursting, generate shock waves that destroy nearby cells.

Non-mechanical crushing method

Enzymatic Method: Using lysozyme and other specific enzymes to break down the cell wall

Chemical Permeation Method: Utilizing surfactants or organic solvents to alter cell membrane permeability

Freezing-Thawing Method: A technique that punctures cell membranes by repeatedly freezing and thawing to form ice crystals.
