Cross-linking reagent: Hetero-bifunctional cross-linking reagents have activated esters and maleimide reactive groups. These functional groups react with amines and sulfhydryl groups of proteins, respectively. Enzyme-labeled haptens are prepared using hetero-bifunctional cross-linking reagents such as EMCS or GMBS. The cross-linking reaction requires neutral pH and mild temperature because it is necessary to maintain enzyme activity and antibody titers in the cross-linking reaction.
