It is specially designed for donors who find it difficult to deliver saliva, such as children. The DNA-assisted kit contains the standard GeneFiX™ components and 2 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 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 GeneFiX™ 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.
