Biotin-PEG4-TFP ester is a biotinylated PEG4 spacer terminated with a tetrafluorophenyl (TFP) activated ester, formulated for conjugation to primary amines in proteins, peptides, or small molecules. It enables rapid formation of stable amide bonds while providing a hydrophilic linker that reduces steric hindrance and improves solubility. The TFP activated ester offers greater hydrolytic stability than many NHS esters, supporting cleaner bioconjugation and linker assembly workflows.

  • Activated TFP ester for efficient coupling to primary amines.
  • Biotin tag for affinity capture and detection.
  • PEG4 spacer improves solubility and reduces steric hindrance.
  • Greater hydrolytic stability than many NHS esters, enabling cleaner conjugations.
  • Suitable for protein, peptide, and small-molecule conjugation applications.
