Cat. No. / ID: 761165
The PAXgene Blood DNA Tube (IVD) is intended to collect, anticoagulate, stabilize, transport, and store a venous whole blood sample for preparation of human DNA for use with molecular diagnostic test methods that require DNA. The performance characteristics of this device have not been established for molecular diagnostic assays in general. Users must validate the use of a product for their specific molecular diagnostic assay. The intended use and claims have been validated with the QIAamp DSP DNA Blood Mini Kit (IVD) and the QIAsymphony DSP DNA Kit (IVD).
The performance of the PAXgene Blood DNA Tube (IVD) has been validated under several processing temperatures and time intervals relevant to variation in blood collection techniques, transport methods and storage conditions. Validation information, along with data from exposure to high temperatures, long-term storage at –20°C and freeze-thaw tests are available under the Resources tab.
The table below summarizes DNA yields from whole blood collected in PAXgene Blood DNA Tubes (IVD) and purified using 2 different technologies. The yield of genomic DNA purified from blood samples collected in PAXgene Blood DNA Tubes (IVD) varies depending on the volume of blood processed, the white blood cell count of the specimen and the selected DNA isolation method.
