Indicating FTA Micro Card, 1 sample area per cardGE Healthcare’s Whatman Indicating FTA Micro Cards collect, stabilize, process, transport, and archive buccal DNA samples.
FTA CardsWhatman 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. Indicating FTA Micro CardFTA cards are available as indicating cards for use with clear samples, such as buccal cells or saliva. The cards include a pink indicating dye that turns to white when a clear sample is applied.
