Magnetic bead DNA isolation is a fast and reliable method for medium to high throughput purification of DNA samples.

Isohelix has developed the Saliva-Mag DNA Isolation kit specifically for DNA saliva samples, achieving a fast and efficient methodology, with the maximum purity and yield required for demanding downstream applications.

The kit includes high binding capacity beads with a large surface area for fast attachment, enabling rapid isolation of intact genomic DNA from GeneFiX sample collectors.

Variable volumes can be processed, from a full GeneFiX 2ml saliva collector, to a 0.5ml saliva aliquot, allowing for flexibility and repeated sampling.

As with all Isohelix DNA isolation kits, no harmful or toxic buffers are used, to allow safe, straightforward sample processing.

To enhance this offering, we have designed a custom magnetic rack, designed to enable the rapid purification of up to 12 full GeneFiX saliva samples, in their original tubes. There is also capacity for 6 microtubes for processing smaller aliquots.

Isohelix has developed a new integrated Buccal DNA collection and Stabilization kit, perfect for at-home DNA Sampling

Utilising the Isohelix high-yield swab matrix to collect buccal cells, the swab is then placed into the innovative RapiDri™ pouch for return shipping, and sealed with the barcoded sticker supplied.

The RapiDri™ pouch stabilizes DNA long term at room temperature, to improve call rates and reduce resampling.

For ease of use, collection instructions are printed on the package, and the contents are Ethylene Oxide treated to ensure no hDNA contamination.

We are very excited to welcome Nina to the team at Isohelix. Nina brings a wealth of experience in life science sampling and customer focus, and will be working face to face with our customers in the UK and Europe, helping them to find the best solution to their DNA sampling workflows through our innovative sample collection, stabilisation and purification products.

We welcome Ann Harrison who is an experienced ISO and IVD Scientist, and will elevate on our current ISO and IVD compliant production processes, complementing the rapidly expanding range of products being manufactured at our facilities in Harrietsham UK.  Ann has previously worked in various Pharmaceutical and Clinical GMP environments and we look forward to her specialist skills being utilized within our growing Isohelix team.

Our new addition to the GeneFiX family, the Saliva Microbiome collectors stabilise bacterial DNA for at least 1 year at room temperature, removing the need for cold storage and complex cold chain logistics.

Instant stabilization, free from any human or bacterial DNA contamination, they provide a snapshot of the saliva microbiome at the moment of collection and are safe for at-home testing when the sample timing can be critical.

Isohelix has developed a new DNA Isolation kit for automated magnetic bead applications. Our development team have recorded great results, and would now like to confirm the performance of the new kit in real world applications.

The GeneFix^TM Collectors are pre-filled with high specification Non Toxic Buffer and uses our Design-patented funnel for spill free use.

Isohelix has developed a new High Throughput Protocol for the rapid manual DNA Isolation of larger saliva volumes using common 96 deep well plates.

Isohelix has seen an increasing number of enquiries from scientists wishing to isolate DNA in large numbers of high volume saliva samples, inexpensively and quickly without having to commit to expensive automated instrumentation.

The GeneFix^TM SalivaPrep2 isolation kit uses a unique and inexpensive chemistry, ideally suited for scaling to higher volume and DNA sample numbers without the losses for DNA Purity and Yields, yet has the added advantage of using centrifuges commonly found in most laboratories.

The registration process included rigorous and exhaustive checks, covering risk analysis, manufacturing specifications, technical product performance and quality control processes.

Tom Hole, CEO of Isohelix comments that “Isohelix has been well established in the marketplace for some time, and the registration of both of these key product lines supports the quality of our product design, manufacture and ongoing development.”

Isohelix manufactures DNA and RNA Collection devices for Saliva and Buccal Cells, together with kits for stabilization and extraction of high purity DNA for research and medical purposes.
