Product Features

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.

 

SAMPLE MATERIAL

up to 100 μl of a DNA sample

 

YIELD

90-99%, depending on DNA fragment length (in the range of 100 bp – 10 kb)

 

DNA FRAGMENT LENGTH

- 100 bp - 10 kb

- DNA fragments in the 50-100 bp and 10-30 kb range can also be purified, as can genomic and plasmid DNA, however the efficiency will be decreased.

 

BINDING CAPACITY

approx. 25 μg DNA

 

TIME REQUIRED

5-10 minutes (including incubation time)      

 

DNA PURITY

A260/A280 ratio = 1.7 – 1.9

 

Principle

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.

 

Quality control

The quality of each production batch (LOT) of 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 PCR and qPCR.
