PAXgene Blood ccfDNA Tube (100)，768115，Qiagen，凯杰

The PAXgene Blood ccfDNA Tube is a plastic, closed, evacuated tube for the collection, anticoagulation, transport and storage of human whole blood samples and the stabilization of ccfDNA. When the tube is used in conjunction with the QIAsymphony PAXgene Blood ccfDNA Kit, the QIAGEN QIAamp MinElute ccfDNA Kit or the QIAamp Circulating Nucleic Acid Kit, high-quality ccfDNA can be isolated for use in downstream analytical assays.

• Single-tube collection, stabilization, transport and storage
• Immediate stabilization of circulating, cell-free DNA (ccfDNA)
• Sample transport and storage at room temperature for up to 10 days
• Standardized preanalytical processing of samples
