GE Whatman 903 Protein Saver Cards

The GE Whatman 903 Protein Saver Cards are designed for the safe collection, transport, and storage of biological samples, specifically blood, serum, or plasma. Each card is equipped with five circular sample spots, each capable of holding approximately 75-80 µL of sample. This ensures that a standard card can hold up to 400 µL of total sample volume, making it ideal for long-term archiving and use in a variety of clinical and research applications, including DNA, RNA, and protein analysis.

The cards are made from a high-quality cotton linter-based paper, which offers a durable and stable matrix for storing biological material at room temperature. This eliminates the need for cold chain storage, providing cost and space-saving benefits for institutions managing large-scale sample collections. Additionally, samples dried on the Whatman 903 cards can be stable for years, allowing for long-term analysis and archiving.

The cards meet strict regulatory and industry standards, including those for newborn screening, ensuring they are well-suited for clinical diagnostic applications. The product has been widely cited in studies for its reliability in sample integrity and reproducibility of results. For enhanced usability, each card includes pre-printed barcodes for easy sample tracking.
