General description
Diethyl Pyrocarbonate (DEPC) is a chemical use to inactivate RNase enzymes and is sensitive to moisture and pH. It decomposes at 155°C, to ethanol and carbon dioxide in aqueous solution. DEPC is also sensitive to ammonia, which causes decomposition to urethane, a possible carcinogen.
Application
Diethyl pyrocarbonate has been used in PCR reaction for treating deionized water, which reduces the risk of RNA being degraded by RNases. It is also used for Dot blot hybridization, to dilute total RNA isolated from different micro-organisms.
Modification reagent for His and Tyr residues in proteins. Robust probe for structural disruptions in dsDNA, reacting with fully or partially unstacked bases.
Biochem/physiol Actions
DEPC is a potent nuclease inhibitor.0.1% solution of DEPC is used to inactive RNase.
It inhibits the ryanodine binding to ryanodine/Ca2+ receptor channels in skeletal muscle in a dose and time dependent manner and increases the Ca2+ permeability of SR vesicles.
It inhibits the ryanodine binding to ryanodine/Ca2+ receptor channels in skeletal muscle in a dose and time dependent manner and increases the Ca2+ permeability of SR vesicles.
Inactivates RNase in solution at about 0.1% (v/v), thus protecting RNA against degradation.

문서
Nuclease-free water (or PCR water) is needed in molecular biology to avoid sample degradation during PCR, sequencing, etc. Ultrafiltration provides a quicker, safer, and more sustainable alternative to DEPC treatment when preparing RNase-free and DNase-free water.

Exposure of junctional sarcoplasmic reticulum (SR) membranes or purified ryanodine receptor to the histidine-specific reagent diethyl pyrocarbonate (DEPC) led to concentration- and time-dependent inactivation of ryanodine binding. The pH-dependence of the inactivation of ryanodine binding by DEPC and the reversal
