FARMINGDALE, N.Y.--(BUSINESS WIRE)--Jan. 19, 2006--Enzo Biochem, Inc. (NYSE:ENZ), announced at its annual meeting today that it has been issued a patent covering processes for producing large quantities of therapeutic proteins or RNAs within living target cells. The unusual property of this invention is that it relies upon signals and regulatory elements that do not otherwise exist within the cell. This may allow for a large yield of the specific molecule desired, either the protein or the nucleic acid. By not bringing recognizable signaling moieties into the cell, it could add an element of efficiency and safety to the process.
