DEPC is a non-specific inhibitor of Ribonucleases (RNases). To reduce degradation of RNA in experiments, water is treated with DEPC. The concentration of DEPC is 0.1%. Ultra-pure molecular biology grade water is treated with DEPC followed by auto-claving. Autoclaving inactivates DEPC by causing hydrolysis of DEPC and release of by-products ethanol and carbon-dioxide. DEPC modifies enzymes containing -NH, -SH, or -OH groups in their active sites. DEPC particularly reacts with Cys, His, Lys, Ser and Tyr residues of proteins. DEPC has a half-life of approximately 30 min in water. DEPC-Treated Water (0.1%) can be used with buffers such as PBS and MOPS but cannot be used with the buffers Tris and HEPES. Tris and HEPES make DEPC unavailable to inactivate RNase. DEPC-treated water should not be added to aqueous solutions of ammonia as it will result in the formation of urethane, a possible carcinogen.
