32 nucleic acid extractor, 2 plate positions

32 nucleic acid extractor, 2 plate positionsWorking method:

Magnetic bead method: This method utilizes magnetic beads surface modified with specific ligands or antibodies to selectively bind and enrich nucleic acid molecules in the sample. By magnetic force, magnetic bead nucleic acid complexes can be separated, washed and desorbed to obtain purified nucleic acids.

There are other ways to extract nucleic acid:

Phenol/chloroform extraction method: This method is suitable for extracting DNA or RNA. The sample is first subjected to cell lysis, and then a phenol/chloroform mixture is added to separate DNA/RNA from the phenol phase. The DNA/RNA in the phenolic layer can be separated by centrifugation and purified by alcohol precipitation.

Alkaline lysis method: This method is suitable for extracting DNA. The sample undergoes cell lysis and is then added to an alkaline solution, where DNA is spun into single strands under alkaline conditions. Subsequently, the DNA was neutralized by acid neutralization and purified by precipitation.
