Citraconic Anhydride is a convenient, reversible amine blocking reagent. This protein modification reagent converts primary amines to amide groups with a terminal carboxylic acid moiety. Citraconic Anhydride reacts with primary amines, such as those found in lysine residues, at pH 7-9. This modification is conveniently reversed at pH 3, rendering a citraconic acid by-product. and returning the amine to its original composition. Alternatively, this reversal can be facilitated in the presence of Hydroxylamine (CovaChem 11304-25).
