Product Overview:

The most convenient way to collect DNA samples for gene sampling is saliva. Currently, the most popular method is to collect samples from saliva. It has the advantages of being painless and non-invasive and has a high acceptance rate. It is more convenient and free, and the acceptance of users is also higher.

Product Description:

This product consists of a saliva collector (sampling funnel + sample collection tube), a sample collection tube cap, and a DNA preservation solution tube.

Saliva Collection Kit for collecting, storing, and transporting DNA from saliva samples at room temperature

The preservation solution can store saliva DNA for two years at room temperature and is suitable for a variety of DNA extraction and purification kits.

The humanized design of the collection funnel conforms to the human mouth, making the collection process simple and easy. There is a leak-proof gasket in the cap to seal against leaks.

Clean workshop production, no DNase, no RNase, no pyrogen

Sterilization method: gamma irradiation sterilization

Instructions:

1. Relax your cheeks and gently rub for 30 seconds to produce saliva;

2. Gently spit about 2ml of saliva into the saliva collection funnel;

3. Care should be taken to avoid excessive foam when collecting saliva (the upper foam is not included);

4. Open the DNA preservation solution tube and unscrew the cap;

5. Pour the DNA preservation solution into the saliva collector, and confirm that the layered interface between the liquid and the upper foam in the sample collection reaches the scale line shown in 4ml;

6. Unscrew the collection funnel from the screw mouth of the saliva collector and remove the funnel (remember to dispose of waste after use to avoid contact and pollution);

7. Tighten the cap of the tube on the sample collection tube, and mix the liquid in the tube upside down to fully mix the DNA preservation solution and the saliva sample to complete the sample collection.

Precautions:

①. Do not eat, drink, smoke, or chew gum within 30 minutes before collecting the saliva sample

②. Most people need 2 to 5 minutes to collect saliva samples according to the above steps.

③. Before starting to collect saliva, please relax your cheeks and gently massage your cheeks with your fingers for 15 to 30 seconds to generate saliva.

④. Confirm that the outer packaging of the saliva sample collection tube is in good condition, check the saliva preservation solution tube, and confirm that there is no leakage. Important note: The saliva collection solution that leaks or is cloudy from the preservation solution should not be used!

⑤. Under room temperature storage conditions, the saliva samples collected by this product can be stored stably for 12 months, and high-quality high-molecular-weight DNA fragments can be isolated within the storage period. Due to individual differences in samples, the specific shelf life of different samples fluctuates.
