Whatman FTA technology consists of two distinct chemistries, both of which have the ability to lyse cells on contact, deture proteins, and protect D from degradation. FTA chemistry contains chemical deturants and a free radical scavenger. With FTA, the D remains tightly bound while proteins and inhibitors are washed from the matrix. There are three options for D alysis with FTA cards: direct amplification, standard amplification with rinsing (punch-in method), and extraction of D from the card.
FTA cards are available as non-indicating cards for use with colored samples, such as blood.
