whatman指示型FTA微型卡 与FTA微型卡样式相同，但当样品采集上去以后，卡的颜色会从粉红色变为白色，起到一种指示作用。推荐用于无色样品，如口腔或培养细胞的核酸采集。 GE 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.
