YALEPIC^® Cervical Exfoliated Cell Storage Tube Type II

Absolutely not. This is the core advantage of our product. The YALEPIC Cervical Exfoliated Cell Storage Tube can stably protect DNA in samples at 4-37 degrees C ambient temperature for up to 2 years. Samples can be sent directly to the testing center at room temperature without cryogenic freezing or dry ice transport, which is very convenient.

The storage tube is broadly compatible with standard-sized cervical brushes and cervical swabs on the market. Simply break the swab head into the preservation fluid in the tube after sampling.

Yes. This preservation fluid preserves intact genomic DNA, which in addition to various HPV genotyping and quantitative PCR tests, is also suitable for DNA methylation detection, gene mutation analysis, chromatin immunoprecipitation, and other downstream molecular biology experiments requiring high DNA quality. However, note that the preservation fluid lyses cells, so it is not suitable for Pap smear examinations requiring intact cell morphology. To preserve intact cell morphology, choose YALEPIC Cervical Exfoliated Cell Storage Tube Type I-N CAT# YS21081.

Although the preservation fluid has undergone safety assessment, it still contains chemical components that inhibit microorganisms and nucleases. If splashed on skin, immediately rinse with copious amounts of running water. If splashed in eyes, rinse and seek medical attention promptly. If spilled on clothing, it may leave stains; wash as soon as possible using standard laundering.

One cervical exfoliated cell storage tube is designed for one cervical swab sample. Placing multiple swabs in the same tube compromises sample integrity and traceability, and may affect cell lysis and DNA release efficiency, resulting in test results that cannot be accurately matched to individuals. Please strictly follow the one-person-one-tube principle.

Our validated stability period is 2 years. Beyond this period, large DNA fragments may begin to slowly degrade. Although samples slightly past the expiration date may still detect some target sequences, we strongly recommend completing testing within the 2-year validity period to ensure high accuracy and reproducibility of results, especially for low-abundance viral load samples.
