Nucleogen Highcon PCR Purification Kit is designed for fast cleanup of DNA fragments from PCR or other enzymatic reactions. Using silica gel membrane technology, Nucleogen Highcon PCR Purification Kit deliver high-purity DNA suitable for use in all applications and highly concentrated DNA using minimal elution volumes.

Principle

Nucleogen Highcon PCR Purification Kits contain a silica gel membrane assembly for binding of DNA in high-salt buffer and elution and elution with low-salt buffer or water. The purification procedure removes primers, nucleotides, enzymes, mineral oil, salts, agarose, ethidium bromide, and other impurities from DNA samples. Silica membrane technology eliminates the problems and inconvenience associated with loose resins and slurries. Specialized binding buffers are optimized for specific applications and promote selective adsorption of DNA molecules within particular size ranges.


Procedure

The Nucleogen Highcon PCR Purification System uses a simple bind-wash-elute procedure. Binding buffer is added directly to the PCR sample or other enzymatic reaction, and the mixture is applied to the Nucleogen Highcon PCR Purification spin column. Nucleic acids adsorb to the silica gel membrane in the high-salt conditions provided by the buffer. Impurities are washed away and pure DNA is eluted with a small volume of low-salt buffer provided or water, ready to use in all subsequent applications.


Applications

DNA fragments purified with the Nucleogen Highcon PCR Purification Kits are ready for direct use in most applications, including:

Automated fluorescent sequencing, including capillary sequencing
Radioactive sequencing
Microarray analysis
Ligation and transformation
Restriction digestion
Labeling
Microinjection
PCR
In vitro transcription
