QIAGEN Launches Blood Dry Storage Products
Product News Sep 03, 2009
QIAGEN launched the QIAsafe DNA Blood Kit to provide easy transport and storage of whole blood at room temperature.
QIAGEN’s QIAsafe DNA Blood Kits are the first dry blood storage available on a matrix. The QIAsafe matrix is a mixture of dissolvable compounds that stabilizes DNA at room temperature. The technology is based on anhydrobiosis, a biological mechanism employed by some multicelluar organisms to enable their survival in a dry state for periods over 100 years.
The QIAsafe matrix is optimally formulated for ambient temperature shipping and long-term storage of DNA. In QIAsafe DNA Blood products this technology is used to preserve DNA for future extractions from blood.
“This is a unique product for researchers in molecular diagnostics, biomedical research and pharma that rely on biobanking,” says Marie McCluskey, global product manager, QIAGEN. “Up to 200 µl of blood can be stored in tubes or 48-well plates. The true advantage comes when the sample is rehydrated for analysis. Researchers will notice a significantly higher yield than with traditional room temperature storage methods.”
The QIAsafe matrix forms a protective seal around the DNA as it dries, in essence shrink-wrapping the sample in a protective coating. Drying occurs at room temperature without requiring any special equipment. “Sample recovery is just a simple rehydration step,” says McCluskey. “The rehydrated samples are ready for immediate use without the need for further purification.”
The QIAsafe Blood DNA Kit is the latest addition to QIAGEN’s portfolio of solutions for human blood and tissue stabilization, storage, fixation and purification.
