QIAcard FTA Elute Indicating Micro (25)，WB120412，Qiagen，凯杰

QIAcard FTA Elute formats allow for compact sample preservation and transport at room temperature. The FTA Elute cards contain a chaotropic salt to lyse cells on contact, denature proteins and protect DNA from degradation. Proteins remain tightly bound while DNA is eluted from the matrix. Low PCR inhibitor concentration enables the detection of pathogens or GMPs. Indicating FTA card format includes a purple dye that turns white when a colorless sample, e.g., buccal cells or saliva, is applied There are two different card formats available for both QIAcard FTA Elute formats (see "Card specifications")

• Room temperature, shipment and preservation of nucleic acids from biological samples
• Subsequent release and elution of nucleic acids from biological samples
• Tailored Buffer chemistry (QIAcard FTA Elute Buffer) for maximal nucleic acid recovery available
• Eluted DNA can be used for sequencing and real-time PCR applications

The combination of QIAcard FTA Elute formats for easy sample collection, room temperature preservation and the use of QIAcard FTA Elute Buffer enables efficient nucleic acid elution for downstream applications such as:

• Rapid DNA isolation
• Biobanking
• Genotyping real-time PCR, STR analysis
• Transgenics/Genetic identification
• Pharmacogenomics
• Expression profiling using RT-qPCR (RNA)
