The EXTRACTME DNA CLEAN-UP kit is designed for the rapid and efficient purification of DNA fragments after enzymatic reactions. It efficiently removes nucleases, enzyme inhibitors, detergents, restriction enzymes, polymerases, divalent ions, salts etc. The purified DNA can be used in common downstream applications. The kit enables the purification of DNA fragments from 50 bp to 30 kb, as well as plasmid and genomic DNA. However purification of fragments smaller than 100 bp and larger than 10 kb will result in decreased recovery rates.
The DNA purification procedure utilises spin minicolumns with membranes which efficiently and selectively bind nucleic acids. In the first step the CB Buffer is added to a DNA sample. It causes proteins to degrade and enables DNA binding to the column membrane. As an added convenience, the binding buffer contains a colour indicator, which facilitates easy monitoring of the solution’s pH for optimal DNA binding. The two-step washing stage efficiently removes impurities and enzyme inhibitors. The purified DNA is eluted using either a low ionic strength buffer (Elution Buffer) or water (pH 7.0-9.0) and can be used directly in all downstream applications such as PCR, qPCR, Southern blotting, DNA sequencing, enzymatic restriction, ligation and so forth or stored until ready to use.
The quality of each production batch (LOT) of the EXTRACTME DNA CLEAN-UP kit is tested using standard QC procedures. The purified DNA concentration, quality and stability are evaluated by gel electrophoresis and spectrophotometer. In addition, the functional quality is tested by qPCR and digestion with restriction enzymes.
