  • Preparing biological samples for analysis
    Patent number: 8663959
    Abstract: Methods and devices for preparing a biological sample for analysis are described. The biological sample from an organism has at least macromolecule having a primary structure that naturally degrades after the sample is removed from the organism. The method includes causing the biological sample to adopt a shape to permit rapid and uniform heating. The shaped sample is then rapidly and uniformly heated, thereby altering a secondary structure of the macromolecule while preserving its primary structure.
