WebThiol groups are abundant in the protein structure, such as cysteine, which can be used for ligand immobilization. The maleimide group undergoes an addition reaction with thiol groups to form stable thioether bonds in Fig. 5.6 [89].The reaction is suitable at a pH range of 6.5–7.5, while at higher pH values some cross-reactivity with amine has been observed … WebOne common conjugation strategy, thiol-maleimide coupling, generates a succinimidyl thioether linker with limited stability under physiological conditions. We have shown in previous work that when a peptide with an N-terminal cysteine is conjugated to a maleimide reagent, a thiazine structure is formed via a chemical rearrangement.
