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.
