Description

This nylon-flocked cervical swab comes with a protective tube and is designed to collect cell samples from a woman’s cervix. The samples are then used for subsequent testing to screen for cervical cancer, chlamydia, and gonorrhoea. The swab is enclosed in the tube to safeguard the specimen during transportation and prevent contamination. A screw cap seals the tube, keeping the sample secure until it is ready for analysis.

Product Description

The Cell-Free DNA Preservation Tube is a direct-draw blood collection tube specifically designed to stabilize cell-free DNA (cfDNA) in whole blood at room temperature. Its proprietary, formaldehyde-free additive immediately prevents cell lysis and nuclease activity, effectively inhibiting the release of contaminating genomic DNA (gDNA) from nucleated blood cells. This ensures that the original cfDNA profile – both in concentration and integrity – is preserved from venipuncture all the way to downstream analysis.

By removing the need for immediate plasma separation and cold-chain transport, the tube simplifies complex pre-analytical workflows in liquid biopsy, non-invasive prenatal testing (NIPT), oncology research, and transplant monitoring. Whether samples are processed within hours or after days at ambient temperature, you obtain high-quality cfDNA that faithfully represents the in vivo circulating nucleic acid population.

Key Features & Benefits

Huachenyang 903 DNA Color Sample Collection Card adopts a unique color technology, the colorless samples such as saliva and body fluid can turn the card from pink to colorless, indicating the area where the sample is located, and have the functions of protein denaturation, cell membrane rupture, DNA adsorption, and inhibiting bacterial growth. The sample can be safely stored for a long time.

Applications

Use for the collection of colorless samples such as body fluids, urine, and spinal fluid, as well as DNA extraction from crime scenes, and collection of plant and animal DNA samples in the field.

Features

• Unique technics: a unique process to indicate a colorless sample collection area.

• Easy to use: only need to spot and dry sample, one hour is enough to purify the DNA.

• Good stability: blood sample could be preserved for over 10 years.

• Functional Test: PCR results of preserved blood sample are the same as fresh blood sample.

• Safe and reliable: lyse the cells and prevent the growth of bacteria and fungi.

• Efficient uses: the DNA bound with the blood collection card can be amplified multiple times.

The Viral Transport Medium provides a pH-balanced environment and contains antibiotics to inhibit bacterial or fungal contamination. Microbeads inside the vial ensure more rapid sample dispersion and elution.

Hanks buffer creates a neutral environment, which helps increase the survival time and infection stability of the virus.
