Qiagen Fta Nucleic Acid Collection

Yes, the Qiagen FTA Nucleic Acid Collection system is designed to enhance biosafety and ensure sample integrity:

• Rapid Inactivation: The cards rapidly inactivate organisms, including bloodborne pathogens, immediately upon contact with the chemically treated surface.
• Microbial Prevention: The chemistry also prevents the growth of bacteria and other environmental microorganisms, which helps maintain the stability and integrity of the captured nucleic acids.
• Integrated Protection: This stabilization actively shields the nucleic acids from common degradation factors like nucleases, oxidative stress, and UV damage.

Yes, the Qiagen FTA cards are specifically engineered to provide robust protection and long-term stabilization for collected nucleic acids (DNA/RNA).

The specialized FTA chemistry embedded in the cards offers comprehensive protection by:

• Protecting Against Environmental Damage: Nucleic acids are shielded from common degradative factors, including nucleases, oxidative stress, and UV light.
• Immediate Stabilization: Upon sample application, the chemicals instantly lyse cells and denature proteins, ensuring the integrity of the sample matrix.
• Enhancing Safety: The chemistry rapidly inactivates organisms, including bloodborne pathogens, and prevents the growth of bacteria and other microorganisms on the card.

Yes, the Qiagen FTA Nucleic Acid Collection cards are suitable for collecting buccal cell samples, typically for DNA capture in research or forensic applications.

Key points regarding buccal cell collection:

• Associated Device: For optimal collection, these cards are often used in conjunction with the EasiCollect device, which is designed to efficiently gather buccal cells and transfer them directly onto the FTA card.
• Stabilization: The specialized FTA cards instantly lyse the cells, denature proteins, and stabilize the nucleic acids, ensuring long-term integrity.
• Storage: This stabilization process allows the preserved DNA/RNA to be stored stably at room temperature, eliminating the need for immediate freezing or refrigeration.

Yes, the Qiagen FTA Nucleic Acid Collection cards are highly effective at enhancing biosafety and sample stability immediately upon application. The specialized chemical matrix is designed to provide rapid protective actions:

• Rapid Organism Inactivation: The cards rapidly inactivate all organisms introduced in the sample, including potentially dangerous bloodborne pathogens. This ensures safer handling, storage, and transport of the samples.
• Microbial Control: They also actively suppress the growth of bacteria and other environmental microorganisms on the card matrix.
• Nucleic Acid Protection: Simultaneously, the integrated chemicals lyse cells, denature proteins, and protect the collected nucleic acids from common degradative agents like nucleases, oxidative stress, and UV radiation.

The Qiagen FTA Nucleic Acid Collection cards are available in two primary packaging quantities, depending on the specific configuration chosen (e.g., Classic, Mini, Micro):

• 25 units per package
• 100 units per package

The Qiagen FTA Nucleic Acid Collection system is available in several specialized configurations, designed to simplify handling and ensure robust stabilization of nucleic acids.

Key card formats include:

• FTA Classic, Mini, and Micro: Standard formats suitable for general collection and long-term preservation.
• FTA Elute Micro Card: A specialized format allowing for the direct elution of purified nucleic acids, streamlining downstream analysis.
• FTA Gene Card: A variant tailored for specific genomic and laboratory applications.
• FTA PlantSaver Card: Optimized specifically for the efficient collection and stabilization of nucleic acids from plant samples.

Additionally, many card types are available as “Indicating” versions, which feature a color change upon sample application to provide visual confirmation of successful saturation. Cards also vary in size, offering 1, 2, 3, or 4 sample areas to accommodate different required sample volumes.

Yes, the specialized chemical matrix in the FTA cards is designed to provide comprehensive sample protection and microbial control.

Key functions include:

• Microbial Growth Prevention: The matrix actively inhibits the proliferation of bacteria and other common microorganisms on the sample material.
• Organism Inactivation: The cards rapidly lyse cells, denature proteins, and inactivate all organisms present, including potentially hazardous bloodborne pathogens.

This comprehensive stabilization allows for safer handling, storage, and transport of nucleic acids at room temperature.

The FTA cards utilize advanced chemical technology embedded in the card matrix to provide comprehensive stabilization and protection for nucleic acids. This robust, immediate, and multi-faceted process includes the following key actions:

• Immediate Lysis and Denaturation: Upon sample application, the chemicals instantly lyse cells and denature proteins, preparing the sample for preservation.
• Robust Protection: The chemistry actively shields the nucleic acids from major environmental and enzymatic threats, specifically protecting against:
  • Nucleases (enzymatic degradation)
  • Oxidative damage
  • UV radiation
• Microorganism Control: For biosafety, the card rapidly inactivates organisms, including bloodborne pathogens, and prevents the growth of bacteria and other microorganisms.

This integrated stabilization ensures the integrity of the nucleic acid sample, simplifying handling and processing for downstream analysis.

The volume capacity varies depending on the card configuration (e.g., Classic, Mini, Gene) and the number of sample spots (1, 2, 3, or 4).

Based on available specifications, the Sample Area Volume (volume per spot) examples include:

• 75 µl (e.g., FTA Gene Card)
• 125 µl (e.g., FTA Classic or Mini Cards)

The Total Volume Capacity for the entire card also varies by configuration:

• 225 µl (e.g., FTA Gene Card, 3 spots)
• 250 µl (e.g., FTA Mini Card, 2 spots)
• 500 µl (e.g., FTA Classic Card, 4 spots)

Yes, the Qiagen FTA Nucleic Acid Collection cards offer flexible packaging options to accommodate various workflow needs, from smaller collection volumes to high-throughput laboratories. The available standard package sizes are:

• 25 cards per pack
• 100 cards per pack

These sizes are offered for most of the available card configurations (e.g., Classic, Mini, Micro, Elute Micro, Gene, and PlantSaver).
