FTA （Flinders Technology Associates）（FTA滤膜，FTA卡）是一种特制的滤纸。 它由专利配方的强力变性剂和螯合剂浸泡，纤维基质上含有特殊的化学物质，当捕捉到细胞后自动将其裂解，并与核酸结合，维持样品中DNA的完整性，保护核酸免于降解，免受核酸酶、氧化剂 ...

FTA cards are a suitable device for SARS-CoV-2 sample collection due to high RNA recovery, RNA stability for 7 days at 20°C and 30°C, sensitive PCR detection of viral RNA compared to direct saliva processing, and the potential for virus inactivation through sample lysis.

With FTA Elute cards, DNA will be eluted into water after purification. The eluted DNA can be used for quantitative DNA analysis. FTA cards and FTA Elute cards utilize patented Whatman technology that simplifies collection, transportation, and storage of biological samples and processing of nucleic acids at room temperature.

QIAcard FTA provides a remarkably easy way to collect, isolate and store nucleic acid samples for analysis. Apply almost any type of biological sample to the FTA matrix and the nucleic acids are instantly captured and preserved without the need for refrigeration.

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.

FTA样本 采集卡 极为方便地解决了常温下样本采集、长期储存、远程运输的问题。 而且FTA技术作为DNA样本采集的金标准而被全球广泛采用，提供可靠的、高效率的DNA分析方案。

FTA ™ Cards contain chemicals that lyse cells, denature proteins and protect nucleic acids from nucleases, oxidation and UV damage. FTA ™ cards rapidly inactivate organisms, including blood-borne pathogens, and prevent the growth of bacteria and other microorganisms.

GE医疗生命科学提供 Whatman FTA 卡、903卡及其辅助工具,包括Omniswab口腔拭子、打孔器、垫板、EasiCollect采样器、纯化试剂等,为血样、口腔细胞、植物样本的长期保存、远程运输及后续分析提供简单可靠的解决方案。

• FTA (Flinders Technology Associates) cards are cotton-based, cellulose paper containing chemicals that burst cells, denature proteins and protect DNA, leaving a sample suitable for molecular identification without the risk of disease contamination.

FTA cards® have proved useful for sample storage and latter identification of pathogens with importance for agricultural, animal and human health: however, for optimal handling, processing, and biosafety measures are not well-established.
