An amine-to-thiol crosslinker with medium-length aliphatic spacer arm
Primetech LLC launches a new heterobifunctional crosslinker, N-ε-maleimidocaproyl oxysuccinimide ester (EMCS), which contains an NHS ester on one end and a maleimide group on the other one. The molecule contains a linear 6-carbon spacer, resulting in 9,4 Å crosslinks between biomolecules.
 
Highlights:
  • NHS ester couples with primary amines at pH 7-9, producing stable amide bonds
  • Maleimides react to thiol groups at pH 6.5-7.5, forming thioether linkages
  • Non-cleavable, soluble in DMSO, DMF
  • Aliphatic spacer has low potential for eliciting an immune response
  • Increased arm length vs. analogous reagents
