DNA and RNA electrophoresis is an important means of nucleic acid research, and it is an indispensable part of nucleic acid probe, nucleic acid amplification and sequence analysis. Nucleic acid electrophoresis is usually carried out in agarose gel or polyacrylamide gel. Yeasen provides complete solution of DNA and RNA electrophoresis based on agarose gel, including agarose, nucleic acid gel stain, and DNA markers. The molecular weight range of DNA Marker covers DNA fragments ranging from 50 bp to 15 kb, which meets most experimental requirements.
