Abstract
An embodiment of the claimed invention is directed to a method that greatly streamlines and reduces costs for tissue preparation, preservation, long-term storage and sample retrieval for molecular analysis using a method based on dried blood spot (DBS) technology. In this method, a small needle punch sample of freshly excised tissue will be homogenized in stabilizing reagent and inserted into a device containing absorbent material and drying agent. This device is suitable for long-term sample storage at ambient temperature and allows for easy removal of sections for biomarker analysis.
