The column design is based on the description of gel filtration for the purification of DNA from nick translation reactions by Sambrook, Each Centri-Sep unit consists of a specially fritted microfuge tube, dry gel, a wash tube and a sample collection tube, all specifically designed for this purpose.

The Centri-Sep gel will provide excellent recovery of DNA fragments with sizes greater than 16 base pairs or 25-mer, while removing > 98 % of salts, NTP's and other unwanted low- molecular- weight impurities.

The column gel is hydrated with either reagent-grade water or a suitable buffer or your choice, and spun in a microcentrifuge or swinging-bucket centrifuge to remove the intersititial fluid. Your sample is then applied to the column and spun again, leaving you not only with a sample purified through removal of low- molecular- weight components, but also exchanged into the buffer of your choice.


Centri-Sep Columns can also be used for the following applications:
  • Removal of excess DyeDeoxy™ terminators
  • Removal of excess BigDye™ terminators
  • Removal of more than 98% of salts and unwanted low-molecular-weight impurities
  • Purification of fluorescent reaction mixtures
  • Removal of free and labeled dNTP's from DNA or RNA, as inon:
  1. nick translation
  2. end-labeling reactions
  3. polymerization reaction
  • Removal of traces of phenol or exchange of buffer salts
  • Purification and desalting of proteins
  • Removal of excess nucleotides and small primers in PCR reactions
  • Removal of radioactive precursors
  • Desalting and buffer exchange
  • These columns are far superior – easy to use, quick protocol, non-toxicity – than phenol/chloroform extraction or ethanol precipitation.
Advantages of Centri-Sep spin column:
  • Processed faster than ultrafiltration columns
  • Rapid and efficient separations
  • Buffer is not preselected
  • Convenient 20-100 µL sample size
  • Dry gel format
  • Room Temperature Storage
  • Microcentrifuge format
Benefits of Centri-Sep spin column:
  • Reliable and consistent
  • Time-saving and convenient
  • Enhanced stability
  • Extended shelf-life
  • No special equipment
  • Extremely versatile.
