MicroSpin G-50 columns are designed for the rapid purification of DNA in desalting, buffer exchange, removal of dye terminators from cycle sequencing reactions and removal of labelled nucleotides from DNA labelling reactions.

  • For rapid purification of labeled DNA (DNA probes of > 20 bases) from unincorporated labeled nucleotides in a volume of 25 to 50 μL using spin-column chromatography.
  • Columns are prepacked with Sephadex G-50 DNA Grade pre-equilibrated in TE buffer with 0.05% Kathon CG/ICP Biocide.
  • Product recovery will be at least 10% lower than that from ProbeQuant G-50 Micro Columns.
  • Can also be used for buffer exchange/desalting of enzymatic reactions (10 to 100 μl) following heat denaturation and phenol extraction.

MicroSpin G-50 Columns, rapid purification of DNA requiring clean-up

Good product yield and purity is obtained with sample volumes from 12-50 μL. They are suitable for any DNA greater than 20 bases in length and will not remove or denature enzymes.
