Indicating FTA Classic Card, 4 sample areas per card
- Improves process efficiency by enabling direct amplification for STR analysis due to immediate DNA capture on the FTA card.
- Includes an inert dye, which turns to white when a buccal sample or saliva is added for easy confirmation of sample addition.
- Immediate stabilization and protection of nucleic acids for long term archiving of samples at room temperature.
- Different card options to support manual or automated processing for versatility and incorporation into current workflows.
Whatman 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.
FTA 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.
