Used for collection; storage and transportation of saliva

Saliva is a complex mixture, it contains not only a variety of proteins, but also DNA，RNA, fatty acids and a variety of microorganisms, etc. The research found that the variety of proteins in blood is also in saliva, the saliva can reflect the variation of various protein levels in the blood. Therefore, it is possible to diagnose the disease, analyze gene through detection of saliva.

1. First of all, extract DNA through exfoliated cells in saliva, rather than the saliva itself. So when collecting saliva specimen, you can try your best to shave the jaw of the tongue as many times as possible, at the same time you can also use teeth slightly to scratch the tongue, to ensure the number of exfoliated cells

2. Guarantee that you didn"t eat, drink or smoke etc at the past 30 minutes, because those behaviors affect the success of collection, it is recommend to gargle at 30 minutes before sampling

3. Take out the sorbent cotton from saliva collection tube

4. Put sorbent cotton in the mouth, absorb fully for 3-5 minutes to stimulate the secretion of saliva, then open the green cover of the collector, spit the sorbent cotton with saliva to the collection tube, tighten the saliva collection tube cover

5. Put the saliva collection tube in the centrifuge, in 500-1000g centrifuging for 2 minutes, to make the saliva in sorbent cotton moved to the lower of collection tube

6. The liquid in the collection tube contains stabilizer, the mixed liquid can be used to analyze for many kinds of experiment

To absorb the saliva by way of put the sorbent cotton in mouth, absorbing 2 ml of saliva in 3-5 minutes. Stabilizer is contained in the collection tube, mixed specimen can be used for DNA detection; drugs detection and infectious diseases detection, etc.
