Chemical Reactivity Amine


  • Cleavable analog of Sulfo-NHS-LC-Biotin
  • Can remove biotin label by cleaving spacer disulfide bond with reducing agents, such as DTT
  • Ideal for affinity purification experiments that require efficient elution from immobilized avidin supports (cleaving disulfide bond releases proteins)
  • Long spacer arm reduces steric hindrance for binding interactions
