Description

Biotinylate primary amines (e.g., protein lysines) and secondary amines such as histidine and tryptophan with this tetrafluorophenyl-ester biotinylation reagent.

Thermo Scientific™ EZ-Link TFP-PEG3-Biotin is a tetrafluorophenyl-ester biotinylatoin reagent that enables labeling at primary amines found on lysine residues and the N-terminus and secondary amines such as histidine and tryptophan.

Highlights:

  • Tetrafluorophenyl (TFP) ester reacts with primary and secondary amines at pH 7-9
  • Long-chain, water-soluble, polyethylene glycol (PEG) spacer arm
  • PEG spacer arm transfers hydrophilicity to final conjugate
  • Creates an amide bond
