QIAGEN QIAcard® FTA® Indicating cards

The QIAGEN QIAcard® FTA® Classic Indicating Cards are advanced sample collection and storage devices designed for the secure capture, preservation, and transport of nucleic acids. Utilizing proprietary FTA technology, these cards are chemically treated to lyse cells, inactivate pathogens, and stabilize DNA, enabling long-term storage at room temperature without the need for refrigeration.

Featuring an integrated color-indicating dye, the cards provide immediate visual confirmation of sample application, ensuring accuracy and traceability during collection. With four sample areas per card, they support multiple sample deposits, making them ideal for forensic investigations, clinical research, and large-scale genetic studies.

Technical Specifications

Available Models and Ordering Information

Workflow Integration

Sample Collection → FTA Card Application → Drying → Storage/Transport → Punch Extraction → PCR / STR / Sequencing

This workflow ensures:

• Safe and stable DNA preservation
• Minimal sample handling
• Rapid transition to downstream analysis

Usage Guidelines

1. Apply biological sample directly onto the card surface
2. Observe color change to confirm proper sample deposition
3. Allow the card to dry completely
4. Store in a clean, dry environment at room temperature
5. For purification workflows, use FTA Wash Buffer prior to amplification if required

Unique Advantages

• Immediate visual confirmation of sample application
• Enables long-term DNA storage without refrigeration
• Reduces need for complex DNA extraction workflows
• Supports high-throughput and field-based sample collection
• Enhances safety through pathogen inactivation
• Trusted solution for forensic, clinical, and research laboratories

Regulatory & Safety Information

• For Research Use Only (RUO) – Not intended for diagnostic or therapeutic use
• Handle samples according to appropriate biosafety protocols
• Store in a clean, dry environment away from contaminants

The QIAGEN QIAcard® FTA® Classic Indicating Cards provide a robust, reliable, and user-friendly solution for DNA collection and preservation. With built-in sample indication, long-term stability, and direct compatibility with PCR-based applications, these cards are an indispensable tool for modern forensic, clinical, and molecular biology workflows.
