Saliva DNA Collection Card

Saliva DNA Collection Card
Saliva Collection Card (Indicator) is a new generation of biological sample preservation card, the card is impregnated with high performance components that indicate the presence of the sample and facilitate the preservation of the sample, which keeps the DNA sample stable under cool and dry conditions, and the pink indicator can be preserved eternally without discolouration, which is convenient for review and retesting and suitable for the use of direct-expansion reagents.
Oral Cell Collection Card is a new type of medium for storing DNA with plant fibre as the carrier, designed for the collection, transportation and storage of samples of various biological fluids, including saliva, cell cultures and other samples at room temperature. Through a unique formulation and production process, when samples containing biological fluids come into contact with the Oral Cell Collection Card, the colour of the card changes from pink to white, indicating the area where the biological samples are present, which facilitates subsequent punching and PCR amplification.

Saliva Collection Card (Indicator) is a new generation of biological sample preservation card, impregnated with high-performance components that indicate the presence of the sample and facilitate sample preservation, which keeps the DNA sample stable under cool and dry conditions, and the pink indicator can be preserved eternally without discolouration, making it convenient for review and retesting and suitable for use with direct-expansion reagents. DNA samples collected can be stored for more than 15 years at room temperature, with low sampling costs and space-saving storage, as well as easy transport and postal delivery.

Product Features:

1. Sensitive and long-lasting colour indication. When biological fluids, including saliva, come into contact with the card, the colour rapidly changes from pink to white, ensuring that subsequent samples can be quickly located in the mouth.
2. a safer and faster DNA collection method that ensures that the material is free of DNA enzymes and amplifiable human DNA.
3. Avoids damage to the sampler during blood sampling and reduces the resistance of the sampled person.
4. safer for the sampler, avoiding contamination of the sampler by viruses that may be present in the blood.

Methods of use:

1. Sampling personnel should fill in the details of the subject on the front and back of the collection card according to the requirements, and pay attention not to open the collection card when writing to prevent contamination of the sample.
2. The subject rinses his/her mouth with water, takes out the oral swab, inserts it into the mouth with the sponge section, and wipes the inside of the cheek 5-10 times, and then wipes the other side of the cheek 5-10 times. Be careful to keep the swab well moistened and use different sides of the swab.
3. Place the buccal swab on the ring of the pink buccal cell collection card, hold the handle of the buccal swab and squeeze it for 10 seconds, then crush it in the same place for 3 times, and you can see that the area of the collection turns from pink to white.
4. After sampling, dry it naturally for 5-10 minutes, then put it into the archive bag and keep it in a cool, ventilated and dry place.
