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.

Isohelix 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.

    Additional for SK-1S

    The Isohelix 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

    Additional for SK-2S

    The 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

    Additional info for SK-3S, SK-4S & SK-5S

    The 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-3S:1 Buccal Swab per wrapper
    SK-4S: 2 Buccal Swabs per wrapper
    SK-5S: 3 Buccal Swabs per wrapper

Additional info on RapiDri™Pouch

The RD-01 Packaging includes a RapiDri™Pouch and bar code for shipping in addition to 1 swab.  Once placed into the RapiDri™ pouch, the swab is quickly stabilized to maximize the DNA yield without loss of integrity, over many months at ambient temperatures. The entire contents are Ethylene Oxide treated and routinely tested for human DNA contamination. The RapiDri™ pouch also protects the DNA from cross contamination and conveniently acts as a transport pack, meeting


The MS-001, MS-002, MS-003, MS-004 Mini DNA Isohelix 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. 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.


    • 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
