Silica Spin Columns

Silica spin columns with unique adsorption capacity and buffer system specifically bind nucleic acids in the presence of high concentrations of chaotropic salts and wash away impurities. After centrifugation, DNA and RNA are eluted from the silica membrane in water or low salt buffer. The result is highly pure DNA and RNA for biological applications such as PCR, real-time PCR, sequencing, Southern blotting, cloning and genotyping.
