Biotin-PEG8-NHS ester is a biotinylation reagent composed of a biotin group linked via an 8-unit polyethylene glycol spacer to an N-hydroxysuccinimide (NHS) ester. The NHS ester reacts selectively with primary amines to form stable amide bonds, making this compound suitable for conjugation to peptides, proteins, and other amine-containing molecules for labeling, affinity capture, and linker applications in degraders research.

  • High purity (99.9%).
  • PEG8 spacer improves solubility and reduces steric hindrance.
  • Reactive NHS ester enables efficient amine coupling.
  • Suitable for protein labeling and affinity purification.
  • Available in small research-scale pack sizes for convenience.
