DNA clean-up

DNA Sequencing - Centri-Sep

Centri-Sep products provide for the effective and reliable removal of excess unincorporated dideoxy terminators from completed DNA sequencing reactions.

Centri-Sep Columns are used in the following applications:

  • Removal of excess DyeDeoxy™ and BigDye™ terminators
  • Removal of more than 98% of salts, phenol and unwanted low-molecular-weight impurities
  • Purification of fluorescent reaction mixtures
  • Removal of free and labeled dNTP's from DNA or RNA
  • Purification and desalting of proteins
  • Removal of excess nucleotides and small primers in PCR reactions

Advantages of Centri-Sep spin columns:

  • Rapid and efficient separation from impurities
  • Faster and more reproducible purification than phenol/chloroform
  • No need to preselect buffer
  • 20-100 µL sample size

Size exclusion separation - Centri-Spin

Centri-Spin size exclusion columns provide a convenient and rapid method to remove excess label from nick translation or PCR labeling reactions. They are used for the fast and efficient purification of larger molecules (proteins, nucleic acids, complex carbohydrates, etc.), from small molecules (nucleotides, buffer salts, etc.)

Centri-Spin columns are used for:

  • FISH transfection probe labeling gene products
  • Signal transduction differential display antibody labeling transformation studies
  • Protein labeling receptor analysis
  • Solid phase array desalting
