| Product Name | Cell-free DNA preservation reagent for prenatal screening and genetic testing, 14-day stability at 4-37°C |
| Catalog No. | ATR-SPS-0073 |
| Description | This cell-free DNA preservation reagent is designed to stabilize cell-free DNA (cfDNA) in blood samples by inhibiting nuclease-mediated degradation. It preserves cfDNA in whole blood for up to 14 days under conditions ranging from 4°C to 37°C, providing a dependable solution for maintaining sample integrity prior to downstream genetic testing. The reagent is widely used in applications such as prenatal screening and molecular testing programs. Samples treated with this preservation reagent can be stored and transported at 4-37°C, and the reagent itself has a shelf life of one year. Compared with conventional blood preservation solutions, it eliminates the need for immediate sample processing and greatly simplifies storage and transportation requirements. |
| Intended Use | Preservation of cell-free DNA in blood samples for downstream genetic testing, widely applied in prenatal screening and related testing programs. |
| Principle / Technology | Inhibits nuclease activity to prevent enzymatic degradation of cell-free DNA, thereby stabilizing cfDNA in blood during storage and transport. |
| Sample Type | Whole blood containing cell-free DNA |
| Performance Range / Specifications | Preserves cell-free DNA in blood for up to 14 days at 4-37°C; samples can be stored and transported at 4-37°C |
| Shelf Life | 1 year |
| Package Specifications | 10 g |
| Key Features | Inhibits nuclease degradation of cell-free DNA Stabilizes blood cfDNA for up to 14 days at 4-37°C Eliminates the requirement for immediate sample processing Simplifies storage and transportation conditions compared with conventional blood preservation solutions Suitable for prenatal screening and genetic testing workflows |
