The IS GFX-1 GeneFiX Saliva collector can collect 1 mL of saliva and has been designed to maximize purity without compromising yield. It stabilizes DNA and RNA at room temperature and is suitable to be used for clinic-based, home, and field sampling. The collection tube is pre-filled with a non-toxic and guanidinium-free stabilization buffer. Furthermore, the collection tubes can withstand 95kPa 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 GeneFiXâ„¢ collection tubes indicate the correct volume of Saliva to be delivered, and the patented design funnel prevents spillages and saliva flows back even when knocked over. 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.
