FTA technology consists of two distinct chemistries, both of which have the ability to lyse cells on contact, denature proteins, and protect DNA from degradation. FTA chemistry contains chemical denaturants and a free radical scavenger. With FTA, the DNA remains tightly bound while proteins and inhibitors are washed from the matrix. There are three options for DNA analysis with FTA cards: direct amplification, standard amplification with rinsing (“punch-in” method), and extraction of DNA from the card.
QIAcard FTA non-indicating cards are designed for the collection, transport and archiving of biological samples such as blood, cells and tissue. DNA remains tightly bound to FTA while proteins and inhibitors are washed from the matrix. Advantages include cell lysis on contact, denaturation of proteins and immediate stabilisation and protection of nucleic acids.
- Convenient collection of blood, plasmid, cells, tissue or plant samples
- Improves process efficiency by enabling direct amplification for STR analysis
- Stabilisation and protection of nucleic acids at room temperature
