QIAGEN QIAcard® FTA® Mini Indicating cards, 2 sample area

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

Featuring two designated sample areas, the Mini format allows for duplicate sampling or parallel testing, making it ideal for forensic casework, clinical studies, and molecular biology applications. The integrated color-indicating dye provides immediate visual confirmation of successful sample application, ensuring accuracy and traceability.

Key Features

Dual Sample Capacity

• Two sample areas per card for redundancy or comparative analysis
• Supports parallel testing and repeat verification
• Enhances reliability in forensic and research workflows

Color-Indicating Technology

• Built-in dye changes color upon sample application
• Provides instant visual confirmation of proper sample deposition
• Reduces sampling errors and improves workflow confidence

Long-Term DNA Preservation

• Stabilizes nucleic acids for extended storage at room temperature
• Protects DNA from degradation, oxidation, and environmental exposure
• Eliminates dependence on cold-chain logistics

Integrated Cell Lysis & Contamination Control

• Chemically treated matrix lyses cells on contact
• Reduces risk of bacterial and fungal contamination
• Enables safe sample handling and transport

Direct PCR Compatibility

• DNA can be used directly in PCR, qPCR, and STR analysis
• Eliminates the need for traditional DNA extraction in many workflows
• Accelerates downstream processing

Applications

• Forensic DNA collection and crime scene investigation
• Human identification and disaster victim identification (DVI)
• Clinical research and biobanking
• Genetic and molecular biology studies
• PCR, STR profiling, and sequencing workflows
• Field-based DNA sampling (epidemiology, veterinary, environmental studies)

Technical Specifications

Available Models and Ordering Information

Workflow Integration

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

This workflow ensures:

• Secure DNA preservation
• Dual-sample redundancy for validation
• Efficient transition to downstream molecular analysis

Usage Guidelines

1. Apply biological sample onto one or both designated areas
2. Observe color change to confirm correct sample application
3. Allow the card to dry completely
4. Store in a clean, dry environment at room temperature
5. Use FTA Wash Buffer if purification is required before amplification

Unique Advantages

• Dual-sample design improves reliability and verification
• Immediate visual confirmation of sample deposition
• Enables long-term DNA storage without refrigeration
• Supports direct PCR workflows, reducing processing time
• Compact and portable for field and forensic use
• Trusted solution for forensic, clinical, and research laboratories

Regulatory & Safety Information

• For Research Use Only (RUO) – Not intended for diagnostic or therapeutic use
• Follow appropriate biosafety procedures during handling
• Store in a clean, dry environment to maintain sample integrity

The QIAGEN QIAcard® FTA® Mini Indicating Cards offer a reliable, flexible, and efficient solution for dual-sample DNA collection and preservation. Combining FTA-based stabilization, visual sample indication, and direct PCR compatibility, these cards are ideal for laboratories and field applications requiring accuracy, redundancy, and long-term DNA stability.
