Spezifikationen

Prinzip

This product utilizes silica gel columns for a rapid and reliable DNA-Reinigung process.

1. Lysis and Digestion: The sample undergoes treatment with a lysate solution and protease. This breaks open cells and degrades proteins, releasing DNA into the solution.

2. Binding to Silica Membrane: 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. Waschen: Wash buffers are passed through the column, removing unbound proteins and cellular debris that didn’t adhere to the silica.

4. Elution: A low-salt buffer (typically 10 mM Tris, pH 8.0) is used to elute the purified DNA from the silica membrane. 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, such as PCR, Southern Blot, and next-generation sequencing.

Vorteile

• Hohe Ausbeute – most optimal process, free DNA (>50bp) can be obtained to the maximum extent
• High concentration – low elution volume, ensuring high nucleic acid concentration
• Hohe Reinheit – low alcohol binding method, completely removing inhibitor and protein pollution
• High recovery – DNA can be recovered at the level of PG by silica gel column purification

Lagerung und Stabilität

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) upon arrival for maximum effectiveness.

Acceptable Short-Term Storage:

• Proteinase K and Carrier RNA can be kept at room temperature (15-25°C) for up to 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 Monate unter diesen Bedingungen.

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.
