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 the purification of 50bp-20kb DNA. DNA recovery is usually up to 95%. Purified DNA are ready for direct use in all applications, including sequencing, ligation and transformation, restriction digestion, labeling, microinjection, PCR, in vitro transcription, hybridization and other subsequent experiments.
