There are many types of nucleic acid extraction kits，such as bacterial genomic DNA extraction kit ,whole blood genomic DNA nucleic acid extraction kit and etc. Today, we will mainly introduce the principle, use method and specific steps of the magnetic bead method nucleic acid extraction kit.
Nucleic acids are widely present in all animals, plant cells, and microorganisms. Nucleic acids in organisms often combine with proteins to form nucleoproteins.
According to different chemical composition, nucleic acid can be divided into ribonucleic acid, referred to as RNA and deoxyribonucleic acid, referred to as DNA. DNA is the main material basis for storing, copying and transmitting genetic information. RNA plays an important role in the process of protein synthesis, among which transfer ribonucleic acid, tRNA for short. Plays the role of carrying and transferring activated amino acids; messenger ribonucleic acid, referred to as mRNA, is the template for protein synthesis. Ribosomal ribonucleic acid, rRNA for short, is the main place where cells synthesize proteins.
