Isohelix DNA Buccal Swabs

Isohelix DNA Buccal Swabs

The Isohelix range of DNA Buccal Swabs has been specifically designed to give increased yields of high quality buccal cell and genomic DNA.

Buccal cell sampling offers a viable alternative to blood collection and together with the Isohelix range of DNA Isolation and Stabilization kits, enables high yields of pure, intact DNA to be collected easily and quickly.

Our DNA swabs are suitable for both human and veterinary use and offer significant advantages over other DNA swab designs in terms of efficiency of cell collection by the unique swab matrix, which combined with a quick release surface, maximizes yields of DNA. 

Swab batches are ethylene oxide treated and routinely tested for human DNA contamination.



  • Unique swab matrix greatly improves DNA yields

  • Human and veterinary use
  • Easy to handle and quick to use
  • Single and twin sterile packs available


  • Research genotyping
  • Veterinary genotyping and diagnostics
  • Paternity and heredity services
  • Forensics and DNA population studies

Isohelix DNA Swab Comparisons




Isohelix SK1 Buccal SwabThe SK-1S DNA swab uses the unique swab matrix design to efficiently collect buccal cell samples.

Following sampling you simply snap the shaft just above the swab head and place into the tube provided, then seal for containment.

DNA Buccal Swab Pack:
1 buccal swab with 5ml tube and cap



Isohelix SK2 DNA Buccal SwabThe SK-2S has the same features as the SK-1S except that it includes a unique cap design which allows you to simply push the entire swab head from off the shaft into the collection tube after sampling.

This format has the advantage of being easier to manipulate at the DNA isolation stage whether using manual or HT extraction methods.

DNA Buccal Swab Pack:
1 buccal swab with 2ml tube and special release cap


SK-3S, SK-4S & SK-5S

Isohelix DNA Swabs SK3, SK4 and SK5The SK-3S, SK-4S and SK-5S formats all use the same design and materials used in the SK-1S and SK-2S formats, and have exactly the same advantages for efficiently collecting buccal cell samples.

Like the SK-1S, you can quickly snap the shaft at the breakpoint if you wish to store the swab in a tube. If this is your preferred method, Cell Projects has available pre capped tubes that can be ordered with these formats.

SK-4S: 2 Buccal Swabs per wrapper
SK-5S: 3 Buccal Swabs per wrapper



MS Mini DNA Swabs

The MS Mini DNA Swabs use exactly the same matrix material as the SK swabs so there is significant history of use but have reduced dimensions and area.

The width of the swab has been reduced from 8mm to 6mm and employs a slightly different shaft attachment enabling a DNA yield close to the SK swabs.

The swabs are ethylene oxide sterilized and are available in different swabs numbers per wrapper, the break point has been reduced compared to the SK swab allowing it to be used in smaller tubes.

  • Small Mammals, invertebrates and other animals
  • Mice genotyping
  • Automation friendly


  • Smaller surface area size
  • Very high pro rata DNA yields
  • Fits smaller tubes so can be 96 racked
  • Lower break point to fit shorter tubes
  • Uses identical swab material to SK series
