Abstract
The present invention provides methods, compositions, and kits for the storage and stabilization of biological molecules. The methods comprise applying Tris(2-carboxyethyl)phosphine (TCEP) to at least one biological molecule bound to a solid substrate and storing in an organic solvent. Preferably, the biological molecules are nucleic acids. Compositions and kits for performing the process according to the invention are also provided.
