    Abstract: A solid matrix for the extraction, stabilization, and storage of nucleic acids is provided. At least one protein denaturant, and at least one acid or acid-titrated buffer reagent are impregnated in a dry state therein the matrix; and the matrix is configured to provide an acidic pH on hydration. The matrix is configured to extract nucleic acids from a sample and stabilize the extracted nucleic acids, particularly RNA, in a dry format under ambient conditions for a prolonged period of time. Methods for collecting and recovering the nucleic acids stored in the dry solid matrix are also described.

    Abstract: A solid substrate for biological sample storage under dry-state and elution of biomolecules is provided. The dry, solid substrate is coated with saccharides, such as monosaccharides, oligosaccharides, polysaccharides or combinations thereof, and the substrate is comprised of one or more protein denaturing agents impregnated therein under a substantially dry state. A method for elution of biomolecules from biological samples is also provided. The compositions disclosed herein provide for enhanced elution and recovery of biomolecules, such as nucleic acids, from the sample. The sample is disposed on a substrate, dried to a substantially dry state; eluted from the biological sample dried on the substrate by rehydrating the substrate in an elution buffer.
