  1. High Stability: The fixative in the reagent effectively stabilizes cell structure, prevents cell rupture and avoids leakage of cellular genomic DNA during the storage and transportation of blood samples.
  2. High Tolerance: Preserve cf-DNA and cf-RNA for 7 days at 10~30℃.
  3. Options Available: Two types of tubes available: 5ml blood draw type (0.9ml reagents added) and 10ml blood draw type (1.8ml reagents added).
  4. Easy Downstream Operation: Extraction can be accomplished using most commercially available kits.
  5. High-performance Reagent: Anticoagulant K3EDTA and inhibitor RNase are added in reagent.
