Single-cell electrophoresis apparatus
It is mainly used for single cell gel electrophoresis, and can be used for research on apoptosis, drug toxicology and carcinogenesis.
1. One electrophoresis experiment can run up to 80 films;
2. High throughput, each loading can hold 10000 single cells for electrophoresis at the same time;
3. Efficient refrigeration device can improve image resolution;
4. Unique film design reduces DNA damage during electrophoresis;
5. The unique humidity control device ensures the stability of the environment in the electrophoresis tank during the electrophoresis process.
3、 Product principle:
Under neutral conditions, DNA fragments can enter the gel for migration. Under the action of alkali treatment and alkaline electrolyte, DNA helices are broken, and damaged DNA strands and fragments are released. Due to the small molecular weight of these DNA, they will leave the nuclear DNA and move to the positive pole in the electrophoresis process, forming a comet like image, while the undamaged DNA remains spherical. The more serious the DNA damage, the more fragments and the smaller the fragments, the larger the amount of DNA transferred during electrophoresis, and the longer the migration distance. Therefore, the damage degree of DNA can be quantitatively analyzed by measuring the length, area or fluorescence intensity of comet tail.
