What are the characteristics of the saliva collector
Saliva collector is also called saliva sampler, saliva collection device, DNA saliva collection tube. Saliva collection will not cause any discomfort to the sampled person and is easily accepted, so it can greatly expand the sampling range of DNA genetic research.
In fact, the saliva collector consists of a funnel, a sampling tube and a disinfectant. Because the funnel can send saliva directly to the non-toxic stable buffer. In fact, there are clear dividing lines on the surface of the saliva collector. Therefore, the unique funnel design can prevent backflow, and the sampler is very convenient, and it is convenient for the transportation and storage of samples.
The saliva collector can be use to collect saliva samples secrete by the oral cavity, and evenly mix the collect saliva with the saliva preservation fluid, ensuring the integrity of the DNA in the saliva sample and the long-term storage at room temperature. After the sample is extract, it is use for clinical in vitro diagnosis.
Note:
Because DNA is not extract from the saliva itself, but from the exfoliate cells contain in the saliva. Therefore, when collecting saliva samples, please try to use your tongue to scrape the upper and lower jaw as many times as possible, and use your teeth to scrape the tongue a little to ensure the number of exfoliated cells. It is recommend that the first thing that happens in the morning is sampling to ensure the sampling success rate, because eating, drinking, smoking and other behaviors in the past 30 minutes will affect the sampling success rate.
Compared with blood samples, saliva sample acquisition is simpler, more convenient, safe, painless, and non-invasive. The method of collecting saliva samples reduces the risk of contamination, and adds the convenience of sampling and inspection. The subject can take samples by themselves. The saliva samples collect by the saliva collector can be use in the saliva preservation fluid to replace blood DNA and are widely use in epidemiological research, characteristic medicine, drug response monitoring, genetic disease diagnosis, disease probability prediction, and healthy life counseling.
Features of saliva collector:
1. Simple: The product sampling process is simple, fast and easy to operate.
2. Flexibility:
Before blood collection, it was only possible to go to a hospital or a testing institution, but the saliva collector can be easily collected in the laboratory, at home, and in the outpatient clinic.
3. Easy to store:
The sample after sampling is stable, can be stored at room temperature, and is very convenient for transportation.
4. Applicable to a wide range of people:
This method is suitable for all kinds of people, especially for children and patients who do not meet the conditions for blood sampling.
5. Safety:
This method can collect samples non-invasively and reduce the chance of infection.
6. Efficient:
Sample processing is easier to purify automatically, and more DNA/RNA of better quality can be obtained.
