Pyrocarbonate de diéthyle, 99% (NT)

Non disponible en dehors du Royaume-Uni et de l'Irlande

Application

Modification reagent for His and Tyr residues in proteins. Robust probe for structural disruptions in dsDNA, reacting with fully or partially unstacked bases.

Diethyl pyrocarbonate may be used in the following studies:For the modification of histidyl residues in proteins.As a nuclease inhibitor, for the extraction of undegraded nucleic acids from etiolated and green plant tissues.For the modification of linear and supercoiled plasmid DNAs.As a chemical probe to investigate the secondary structure in negatively supercoiled DNA.For cabethoxylation of histidine residues of actin.

Biochem/physiol Actions

Inactivates RNase in solution at about 0.1% (v/v), thus protecting RNA against degradation.

General description

Diethyl pyrocarbonate (DEP) is a bactericidal agent and decomposes in water to CO₂ and ethanol. DEP inhibits enzymes such as DNase and RNase without affecting nucleic acids. It is useful for the preparation of mRNA from tissues.
