Application

Thiol-PEG8-acid serves as a versatile bifunctional linker for bioconjugation and surface functionalization. The thiol group enables site-specific coupling via maleimide or gold-thiol chemistry, while the terminal carboxylic acid facilitates amide bond formation with amines under standard coupling conditions. Its PEG8 spacer provides enhanced solubility and reduced non-specific binding, making it ideal for conjugating peptides, antibodies, or small molecules in aqueous environments. Bench-stable and readily purified by precipitation or dialysis, Thiol-PEG8-acid supports robust workflows in drug delivery and diagnostic probe development.
