Qiagen, WB120305, QIAcard FTA Classic (25), 4 sample areas per card

Non-Indicating QIAcard FTA formats stabilize, process, transport and archive colored samples such as blood. QIAcard Indicating FTA formats include a pink dye that turns white when a colorless sample, e.g., buccal cells or saliva is applied. FTA technology enables cell lysis on contact, denatures proteins and confers immediate stabilization and protection of nucleic acids. DNA remains tightly bound to FTA while proteins and inhibitors are washed from the matrix. There are 3 different card formats available for both QIAcard FTA formats, Indicating and Non-Indicating: Classic (4 sample areas per card) Mini (2 sample areas per card) Micro (1 sample area per card) Each sample area of a card can be processed separately. This versatility of handling supports manual or automated processing and incorporation into current workflows.
FTA (Flinders Technology Associates) is a chemically coated cellulose matrix. The impregnated chemistry is able 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 using the QIAcard FTA Wash Buffer.
