HiPure Circulating DNA Mini Kit, designed to efficiently purify short, cell-free DNA (cfDNA) molecules from human biological fluids:

• Target:
  • Tumor-derived cfDNA fragments and mRNAs in blood
  • Fetal nucleic acids in maternal blood
• Compatibilité des échantillons:
  • Human plasma
  • Human serum
  • Human urine
  • Samples can be fresh or frozen (once only)
• Focus on Short DNA: The kit isolates short nucleic acids (<1000pb) commonly found in biofluids.
• Efficient Purification: The protocol allows for effective recovery of cfDNA from various biofluids.
• Ready for Downstream Use: Purified cfDNA is suitable for diverse applications, y compris:
  • RAP and other amplification reactions
  • Next-generation sequencing (NGS) analyses

Avantages:

• Optimized for Short cfDNA: Specifically designed to capture short DNA fragments relevant for biomarker discovery and liquid biopsies.
• Compatibilité des échantillons larges: Works effectively with various human biofluids, offering flexibility in sample selection.
• Flux de travail rationalisé: The miniaturized kit format allows for faster processing compared to larger kits.

This kit empowers researchers to study circulating DNA in various fields, y compris l'oncologie, non-invasive prenatal testing (NIPT), and liquid biopsy applications.

Caractéristiques

Principe

This product utilizes silica gel columns for a rapid and reliable Purification de l'ADN process.

1. Lyse et digestion: The sample undergoes treatment with a lysate solution and protease. This breaks open cells and degrades proteins, Libérer l'ADN dans la solution.

2. Liaison à la membrane de silice: The lysate containing the DNA is transferred to an adsorption plate or filtration column. The silica membrane in these tools selectively binds DNA molecules due to favorable interactions, while proteins and other impurities pass through.

3. Lavage: Les tampons de lavage sont passés à travers la colonne, removing unbound proteins and cellular debris that didn’t adhere to the silica.

4. Élution: A low-salt buffer (typiquement 10 MM Tris, pH 8.0) est utilisé pour éluer l'ADN purifié de la membrane de silice. This disrupts the interaction between DNA and the silica, allowing the collection of purified DNA in a separate tube.

This method provides a valuable tool for researchers working in various fields that require purified DNA for analysis, comme PCR, Southern Blot, et séquençage de nouvelle génération.

Avantages

• Haut rendement – processus le plus optimal, ADN libre (>50pb) peut être obtenu dans la mesure maximale
• Haute concentration – faible volume d'élution, assurer une concentration élevée d’acide nucléique
• Haute pureté – méthode à faible liaison alcoolique, éliminant complètement la pollution par les inhibiteurs et les protéines
• Récupération élevée – DNA can be recovered at the level of PG by silica gel column purification

Stockage et stabilité

Here’s a quick guide on storing your DNA extraction kit to ensure it functions at its best:

Ideal Storage:

• Store Proteinase K and Carrier RNA in the refrigerator (2-8°C) dès votre arrivée pour une efficacité maximale.

Acceptable Short-Term Storage:

• Proteinase K and Carrier RNA can be kept at room temperature (15-25°C) pour jusqu'à 12 weeks without impacting their performance.

Storing Remaining Components:

• All other kit components should be stored dry at room temperature (15-25°C).
• They will remain stable for at least 18 mois dans ces conditions.

Important Notes:

• If storing the entire kit at 2-8°C, remember to redissolve buffers before use.
• Always ensure all buffers reach room temperature before using them for optimal results.

By following these storage recommendations, you can guarantee your DNA extraction kit is always ready for use and delivers the best possible results.
