GE Whatman FTA WB129241 DMPK-A Cards for Dried Blood Spot (DBS) DNA Analysis and Archiving (Pack of 100)

Description

Product Overview

The GE Whatman FTA WB129241 DMPK‑A cards are engineered for high‑performance dried blood spot (DBS) sampling, a technique that has become essential in modern toxicokinetic and pharmacokinetic studies. Each card is coated with a chemically treated matrix that instantly lyses cells, stabilizes nucleic acids, and protects DNA from degradation, allowing researchers to collect, store, and ship samples without the need for cold chain logistics. The cards measure 5.9 x 5.5 x 3.8 inches and weigh only 0.01 ounces, making them lightweight and easy to handle in any laboratory environment.

Designed specifically for DNA analysis, the FTA cards incorporate a proprietary formulation that inactivates nucleases and preserves the integrity of genetic material for months, even at ambient temperatures. The DMPK‑A designation indicates suitability for drug metabolism and pharmacokinetic (DMPK) applications, where precise quantification of DNA from small blood volumes is critical. The pack contains 100 individual cards, each pre‑printed with a unique identifier to facilitate sample tracking and data management across large studies.

Key specifications include a model number WB129241, a best‑seller rank of #70 in the Assay Kits category, and compliance with GE Healthcare Life Sciences quality standards. The cards are compatible with standard DBS punching equipment and downstream PCR or sequencing workflows, ensuring seamless integration into existing laboratory pipelines. Their robust design also allows for easy archiving, providing a reliable record of biological samples for future reference or regulatory audits.

Usage

These FTA cards are ideal for laboratories conducting toxicokinetic studies, clinical research, forensic investigations, and any application that benefits from low‑volume blood sampling. By requiring only 10 to 20 µl of blood per spot, the cards reduce the burden on animal subjects, enabling researchers to obtain multiple time‑point samples from a single animal without the need for extensive satellite colonies. This not only aligns with ethical considerations but also improves data consistency by minimizing inter‑animal variability.

In practice, a small drop of whole blood is applied to the designated sampling area on the card, where it spreads uniformly across the treated matrix. The sample is then allowed to dry for a few minutes before being sealed in a protective pouch. Once dried, the cards can be stored at room temperature for extended periods, eliminating the need for refrigeration or specialized storage containers. When analysis is required, a single 3 mm punch is sufficient to extract DNA for downstream PCR amplification, sequencing, or quantitative assays.

FAQ

What volume of blood is required per card?

The FTA cards are optimized for micro‑volume sampling and require only 10 to 20 µl of whole blood per spot. This low volume is sufficient to generate high‑quality DNA for most downstream applications, including PCR and next‑generation sequencing.

Can the cards be used for RNA analysis?

While the primary design of the FTA cards focuses on DNA preservation, the matrix also offers some protection for RNA. However, for highly labile RNA targets, dedicated RNA preservation cards are recommended to achieve optimal results.

How long can the dried blood spots be stored at room temperature?

Under standard laboratory conditions (20‑25 °C, low humidity), the cards can maintain DNA integrity for up to 12 months. For longer archival periods, storing the cards in a desiccated environment further extends stability.

Are the cards compatible with automated punching systems?

Yes, the cards are fully compatible with most commercial DBS punching devices. The uniform thickness and consistent matrix composition allow for reliable automated punching, reducing manual handling time and improving throughput.

What support does GE Whatman provide for method development?

GE Whatman offers a suite of technical resources, including detailed protocols, troubleshooting guides, and direct access to scientific support staff. Customers can also request custom method development assistance to tailor the DBS workflow to specific assay requirements.
