MicroSpin G-25 columns are designed for the rapid purification of DNA for use in a wide range of applications, including desalting, buffer exchange, and removal of unincorporated nucleotides from end-labelled oligonucleotides.

• Excellent for rapid buffer exchange/desalting: for example, of PCR amplification products and other DNAs in a volume of 10 to 100µL using spin-column chromatography
• Excellent for rapid DNA purification: especially newly synthesised oligonucleotides > 10-mers in 100 to 150µL of deprotection solution
• Convenient: Prepacked with Sephadex G-25 DNA Grade and pre-equilibrated in distilled water containing 0.05% Kathon CG/ICP Biocide
• Ready to use: requires less than 4 minutes from sample application to collection of purified oligonucleotides
• Tested in assays: including nickase, single- and double-stranded exonuclease, and RNase
• Use additionally: for desalting/buffer exchange of DNA and removal of unincorporated radi-onucleotides from end-labeled oligonucleotides (at least 10 bases in length) in a volume of 10 to 100µL
