Product Description

YALEPIC® CSF cfDNA Storage Tube is designed for the preservation of genomic DNA as well as circulating cell-free DNA (cfDNA) in  cerebrospinal fluid (CSF) samples. Once collected, cfDNA remains stable for up to 7 days at 4-37°C. The tube is formulated with EDTA anticoagulant and specialized preservatives that effectively inhibit nucleases in urine, preventing genomic DNA release from exfoliated cells present in the sample. This non-invasive, convenient solution allows for easy, ambient storage and transport, providing a robust option for urine sample management. Ideal for non-invasive prenatal screening and early disease detection research.

Features

  • Extended Stability: Special preservative ensures cfDNA stability for up to 7 days at 4-37℃.
  • Flexible Isolation Options: Compatible with commercially available cfDNA isolation kits.

Application

Cerebrospinal fluid (CSF).

Storage

Transport at room temperature;

Storage at 10-30℃  for one year.

Must CSF cfDNA storage tubes be refrigerated for transport after sampling?

No. The product is compatible with 4-37 degrees C room temperature transport and storage, without cold chain or refrigeration. Room temperature logistics is sufficient, and cfDNA stability is not affected by temperature fluctuations within 7 days.

How long can cfDNA be stably preserved after CSF samples are placed in the storage tube?

Under 4-37 degrees C room temperature conditions, cfDNA can be stably preserved for 14 days, and genomic DNA in the sample can be stably preserved for up to 1 year, meeting sample retention and batch delivery needs.

Will the storage tube affect downstream cfDNA extraction and NGS sequencing results?

No. The built-in protectant has no nucleic acid inhibition, does not interfere with enzymatic reactions, and is compatible with mainstream commercial nucleic acid extraction kits. The extracted product has complete purity, is compatible with PCR, NGS, and all downstream detection, with accurate and unbiased results.

Can the storage tube prevent cellular genomic DNA from contaminating cfDNA samples?

Yes. The proprietary formulation firmly maintains the integrity of nucleated red blood cells and nucleated cells, inhibiting cell lysis and preventing gDNA release into cfDNA, reducing detection background interference at the source.

What are the product specifications and packaging, and is bulk purchasing supported?

Catalog number YS21031, specification 10 ml/tube, 100 tubes/box, standard industrial packaging. Bulk purchasing by hospitals, laboratories, and testing institutes is supported, with proper certifications and COA quality reports available.

What is the shelf life of unopened storage tubes at room temperature?

In a dark, dry environment at 10-30 degrees C, unopened products have a shelf life of up to 18 months from the manufacturing date. Storage conditions are flexible, with worry-free stocking.

Besides CSF, can it be used for cfDNA preservation in other body fluid samples?

This product has a CSF-specific formulation and is not recommended for blood, urine, bronchoalveolar lavage fluid, or other body fluids. Our company has dedicated cfDNA storage tubes for other body fluids available for inquiry and purchase.

Is the sampling operation complex? Does it require specialized training?

The operation is simple. Just add the collected CSF directly to the storage tube. No additional reagents are needed, and no centrifugation pretreatment is required. Clinical healthcare workers and laboratory personnel can perform it quickly.
