Application field of saliva collector for gene detection

Saliva sample collection is a harmless and painless method to obtain DNA/RNA. This method will not cause any discomfort to the collected person, and it is easy to be accepted, so it can maximize the sampling range of genetic research.The most convenient way to collect DNA for genetic testing is saliva, followed by blood. At present, saliva samples are generally collected for testing. The advantages are painless and non-invasive, and people’s acceptance rate is high. Compared with blood collection, saliva collection is more convenient and free, and users’ acceptance rate is also higher.

The saliva collector is mainly composed of a collecting funnel, a collecting tube and a collecting tube cover. When the preservation liquid is mixed with saliva, it can be preserved for a long time at room temperature, and the DNA/RNA of saliva sample is not damaged. This product is green and easy to carry.

Do not eat, drink tea, smoke or chew gum within 30 minutes before DNA samples are collected and extracted from saliva. Do not tear off the plastic film on the funnel cover. Before spitting, relax your cheeks and gently knead for 30 seconds to produce saliva. To promote cells to shed oral mucosa, and then spit, saliva DNA sample collection tube.

Collection method: 1. Gently spit the saliva of oral endocrine into the oval mouth of saliva collector, and pay attention to avoid excessive foam when collecting saliva. 2. Collect saliva until the layered interface between the saliva in the collecting tube and the upper foam reaches the scale line shown by 2ml.3. Fasten the cover of the collector filled with preservation solution evenly to the oval collection port, and there is a slight click sound when it is buckled. Meanwhile, if the preservation solution flows into the collection pipe evenly, it means that the cover has been buckled. Otherwise, it is necessary to gently open the cover of the collector, and then buckle it evenly again until the preservation solution flows into the collection pipe evenly.
