SDP

DBCO-CONH-S-S-NHS ester is a cleavable disulfide-containing ADC linker that combines a DBCO group for strain-promoted alkyne-azide cycloaddition (SPAAC) with an N-hydroxysuccinimide (NHS) activated ester for conjugation to amines.

  • Provides a cleavable disulfide spacer for controlled payload release.
  • Enables copper-free click chemistry via DBCO for bioorthogonal conjugation.
  • Contains an NHS-activated ester for efficient amine coupling.
  • High reported purity supports sensitive bioconjugation workflows.
  • Soluble in DMSO at high concentrations for easy handling and stock preparation.
  • Stable when stored protected from light and under inert atmosphere at low temperatures.
