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).

  • EGS Crosslinker

    Ethylene glycol bis(succininic acid) N-hydroxysuccinimide ester) is a cleavable, homobifuntional crosslinker that contains two NHS functional groups. The NHS functional groups of EGS are selectively reactive towards primary amines at pH 7 to 9. EGS is cleavable with hydroxylamine at pH 8.5. EGS is often used as a cleavable option when disulfide containing crosslinkers, such as DSP (CovaChem 13304) and DTSSP (CovaChem 13303) are not an option due to the desire to retain disulfide networks of a protein intact.
