Learn how to use this product


The Isohelix DNA GeneFiX Assisted Saliva collector can collect 1 ml of saliva and has been designed to maximize purity without compromising the yield. It stabilizes DNA and RNA at room temperature and is suitable to be used for clinic-based, home, and field sampling. It is specially designed for donors who find it challenging to deliver saliva, such as children.The DNA-assisted kit contains the standard GeneFiX™ components and two absorbent swabs to assist the saliva collection. The swab is simply squeezed against the inside of the funnel to release the saliva into the pre-filled and fully tested Non-Toxic 1ml of the stabilized buffer.


The collection tube is pre-filled with a non-toxic and guanidinium-free stabilization buffer. Furthermore, the collection tubes can withstand 95k Physical pressures specified for leakproof sample transport. The tube has a simple screw-on funnel that delivers the saliva sample directly and quickly into the buffer. It requires no specialist supervision, making remote sampling possible.
Clear, legible markings on the GeneFiX™ collection tubes indicate the correct volume of Saliva to be delivered. The patented design funnel prevents spillages, and saliva flows back even when knocked over.

Saliva collectors: what are the benefits 

When compared against other saliva collectors, the total DNA yields compare favorably and, in many cases, show higher yield data. Another significant benefit of the Genefix stabilization buffer is that it will integrate seamlessly into the various chemistries from Isohelix and directly into most other standard and commercial chemistries at their Proteinase K incubation step.
