SCIENTZ-2CS 基因电穿孔器

Product  Description
The SCIENTZ-2CS Gene Electroporator consists of the main unit, gene electroporation cup, and dedicated connecting cables. It primarily uses electroporation to introduce DNA into competent cells, plant and animal cells, and yeast cells. Compared to other methods, the gene electroporator offers high repeatability, high efficiency, ease of operation, and precise control. Additionally, electroporation has no genotoxicity, making it an essential technique in molecular biology.
Working   Principle
Electroporation, also known as cellular electroporation, is a key method for introducing exogenous macromolecules like DNA, RNA, siRNA, and proteins, as well as small molecules, into cells.
Under the influence of a transient strong electric field, the cell membrane becomes permeable, allowing charged exogenous substances to enter the cell in a manner similar to electrophoresis. Due to the high resistance of the cell membrane’s phospholipid bilayer, the voltage across the cell is mostly borne by the membrane, with minimal voltage in the cytoplasm. This leads to negligible cytotoxicity during electroporation under normal conditions. Once DNA or other substances pass through the membrane, they stay near the membrane before the cell’s mecha- nisms transport them to the nucleus or other parts of the cell.
Since electroporation relies on physical methods, the molecular characteristics on the cell surface have minimal effect on the process. Unlike chemical transfection or viral vector methods, electroporation can be applied to all cell types and is easily quantifiable.
Cell Electroporation Electric Field Diagram
1 The cell membrane acts as an insulator, causing the electric current in the electroporation fluid near the cell to distort.
2 In a series circuit, the larger the resistance, the higher the voltage; most of the voltage is borne by the cell membrane.
3 Only one end of the cell is effectively electroporated.
4 The voltage in the cytoplasm is minimal; DNA halts at the membrane after electroporation and slowly diffuses into the cell via cellular mechanisms.
5 The voltage at the nuclear membrane is extremely low, with no voltage inside the nucleus, resulting in no genotoxicity during electroporation.
