Cell Free Dna Collection Tube

Designed for Plasma cfDNA: These tubes are specifically tailored for collecting plasma cell - free DNA (cfDNA) samples. After venous blood is drawn into the tube, it is optimized to facilitate the isolation and preservation of cfDNA, which is crucial for downstream genetic analysis. This targeted design differentiates them from general - purpose blood collection tubes.

Nuclear Cell Stabilization: They contain additives or have properties that can stabilize nuclear cells in the collected blood sample. By doing so, they prevent the unnecessary release of DNA from cells during storage and transportation. This helps to maintain the integrity of the sample and ensures that the measured cfDNA is truly cell - free and representative of the target genetic material.

Preservation of cfDNA: The tubes are engineered to enhance the overall stability of the sample. They can protect cfDNA from degradation caused by factors such as enzymes, temperature changes, and oxidative stress. This stability is important because cfDNA is relatively fragile, and maintaining its integrity over time allows for accurate and reliable analysis even if there are delays between sample collection and testing.

Consistent Sample Preparation: They play a role in minimizing the risk of variation during cell - free DNA sample preparation. Consistent tube properties, such as the type and amount of additives, as well as the tube's physical characteristics (e.g., material, internal surface), contribute to reproducible results. This reduces the likelihood of errors or inconsistent data that could arise from differences in sample preparation conditions, which is essential for reliable genetic testing, such as in cancer screening or prenatal testing.
