Magnetic DNA Gel Extraction Kit

EmerTher Magnetic DNA Gel Extraction Kit is used to purify DNA fragments from agarose gel following gel electrophoresis. The kit contains superparamagnetic nanoparticles, which are coated through a unique process, enabling strong binding with DNA fragments with little to no non-specific binding. 
Extraction process is simple and fast: add Gel Solubilization Solution to dissolve agarose gel; DNA fragments are then extracted by magnetic beads. The kit is suitable for purification of 50bp-20kb DNA. DNA recovery is usually up to 95%. Purified DNA are ready for direct use in downsteam applications, including sequencing, ligation and transformation, restriction digestion, labeling, microinjection, PCR, in vitro transcription, hybridization and other subsequent experiments. 

Product Features
  • High-speed: fast purification of DNA fragments from agarose gel 

  • High yield: 25 µl of magnetic beads can bind 10 μg DNA

  • High recovery: recovery of DNA fragments is up to 95%

  • High quality: Purify DNA fragments have high quality and show reliable performance in PCR, restriction enzyme digestion, cloning, and labeling, etc.

  • Automation: no liquid-liquid mixing and separation process; therefore, the whole procedure can be easily automated
