Desthiobiotin-NHS ester is an amine-reactive biotinylation reagent (N-hydroxysuccinimide ester) used to covalently label primary amines on proteins and other biomolecules. The desthiobiotin tag binds streptavidin with lower affinity than biotin, allowing reversible capture and mild elution for affinity workflows. The compound is provided as a dry solid intended for storage at low temperature and use in standard bioconjugation protocols.

  • Reacts with primary amines to form stable amide bonds.
  • Enables reversible streptavidin-based capture and mild elution.
  • High purity for reliable conjugation results.
  • Suitable for protein labeling, affinity purification, and probe construction.
  • Available in small-scale packages for laboratory use.
