SDP

Biotin-PEG11-amine is a biotin-labeled, PEG-based PROTAC linker. It is designed for use in the synthesis of PROTACs. PROTACs are compounds that exploit the intracellular ubiquitin-proteasome system to selectively degrade target proteins by connecting a ligand for an E3 ubiquitin ligase and a ligand for the target protein.

  • Biotin-labeled, PEG-based PROTAC linker
  • Used in the synthesis of PROTACs
  • PROTACs selectively degrade target proteins
  • PROTACs utilize the ubiquitin-proteasome system

SDP

Biotin-PEG8-azide is a biotin-labeled polyethylene glycol (PEG8) linker with a terminal azide group used for biotinylation of macromolecules via azide-alkyne cycloaddition (click chemistry). It enables efficient conjugation for affinity capture, detection, or immobilization in biochemical assays.

  • Provides a PEG8 spacer to improve solubility and reduce steric hindrance.
  • Contains a terminal azide for copper-catalyzed or strain-promoted click reactions.
  • Facilitates biotin labeling for high-affinity capture with streptavidin or avidin reagents.
  • High purity (98.8%) suitable for research applications.
  • Off-white to light yellow oil with storage recommendations for long-term stability.
