The?YALEPIC? Vacuette Blood Collection Tube (Cell-Free DNA Storage Tube)?is designed for direct blood sample collection and transport, stabilizing cell-free DNA (cfDNA) with an EDTA anticoagulant and specialized preservative. This formulation effectively inhibits nucleases in plasma and prevents the release of genomic DNA from nucleated blood cells. The product is ideal for studies related to non-invasive prenatal screening, tumor screening, and early diagnosis of various diseases. Samples collected in the preservation solution are compatible with most commercial kits for cfDNA extraction, and the resulting cfDNA is suitable for downstream detection and analysis. Additionally, the product also preserves genomic DNA from nucleated blood cells.
