GE Whatman WB120306 Indicating FTA Classic Card - 4 Sample Areas, 500µl Capacity (25-Pack) | DNA/RNA Collection & Forensic Evidence Preservation

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.

Improves process efficiency by enabling direct amplification for STR analysis

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
