- Sulfonated analog of EMCS has improved solubility in aqueous buffer systems
- Sulfo-NHS ester end couples with primary amines at pH 7-9 to form stable amide bonds
- Maleimide reacts with -SH groups at pH 6.5-7.5, forming stable thioether linkages
- Non-cleavable
- Increased sphere of coupling vs. Sulfo-GMBS
- Aliphatic spacer offers low potential for eliciting an immune response
- Reactive groups: maleimide and Sulfo-NHS ester
- Reactive toward: sulfhydryl and amino groups
