Large DNA Fragments Extraction Kit

The Large DNA Fragments Extraction Kit is a PCR Cleanup Kit and Gel Extraction Kit in 1 convenient system optimized to recover or concentrate a broad range of DNA fragments (100 bp-50 kb) from agarose gel, PCR, or other enzymatic reactions. The Large DNA Fragments Extraction Kit uses a concentrated sodium buffer to dissolve agarose gel and denature enzymes. DNA fragments are then bound by silica beads. Contaminants are removed with a Wash Buffer (containing ethanol) and the purified DNA fragments are eluted by a low salt Elution Buffer, TE or water. Salts, enzymes and unincorporated nucleotides can be effectively removed from the reaction mixture without phenol extraction or alcohol precipitation. Typically, recoveries are up to 80% for Gel Extraction and up to 95% for PCR Cleanup. The entire procedure can be completed in 20 minutes and DNA can be eluted in (10-20 μl) of Elution Buffer to obtain a high concentration of DNA products. The purified DNA is ready for use in PCR, Fluorescent or Radioactive Sequencing, Restriction Enzyme Digestion, DNA Labeling and Ligation.
