YALEPIC^® Oral Swab DNA Sample Storage Tube

Suitable for all populations including adults, children, and infants. Using a non-invasive oral mucosa scraping method, no blood draw is needed. It is trauma-free, painless, gentle, and non-irritating, suitable for all ages.

Under standard 4-37 degrees C room temperature conditions, oral sample DNA can be stably preserved for up to 2 years. It can withstand short-term summer high-temperature exposure and long-distance logistics high-temperature environments. The specialized preservation fluid effectively inhibits nucleases, preventing DNA degradation and fragmentation.

No cold chain or refrigeration/freezing required. The entire process of transport, sampling, and long-term storage can be completed at 4-37 degrees C room temperature, significantly saving cold chain logistics and storage costs.

After sampling, break the swab head at the pre-scored breakpoint, completely immerse it in the preservation fluid in the storage tube, and tighten the cap. The operation is simple, requires no additional tools, and effectively prevents sample contamination.

Compatible with the vast majority of downstream molecular biology experiments, including conventional PCR, qPCR, gene chip analysis, next-generation sequencing (NGS), SNP genotyping, genetic disease screening, paternity testing, and more.

Model YS21052 specification is 2 ml/tube, with each tube containing 1 ml of preservation fluid, 50 tubes/box. Bulk procurement by laboratories and testing institutions is supported. Contact customer service for bulk pricing and customization services.

Avoid eating, drinking, chewing gum, or smoking for 30 minutes before sampling. Rinse the mouth with clean water. During sampling, avoid touching teeth or tongue, and only scrape the inner buccal mucosa to ensure adequate sample cell concentration.

Unopened original products should be stored at room temperature in a cool, dry place, with a shelf life of 3 years. Avoid damp, direct sunlight, and hot, stuffy environments. No refrigeration is needed for normal storage.

The tube features a screw-sealed leak-proof cap design, with pressure-resistant and drop-resistant tube walls. The sealing performance is excellent, and no leakage or seepage will occur during routine courier transport or bumpy handling. Sample safety is guaranteed.

Conventional dry swabs are susceptible to environmental humidity, bacterial growth, and rapid DNA degradation. This product contains a dedicated DNA preservation fluid that can sterilize, inhibit enzymes, and lock in nucleic acids, with longer preservation periods and higher sample purity. No drying process is needed; samples can be sealed immediately after sampling, suitable for long-distance transport to remote testing facilities.
