Features and Benefits
Thiol-dPEG4-acid is a sulfhydryl-containing, crosslinking PEGylation reagent that has a cross-bridge of monodisperse polyethylene glycol. The single molecular weight, discrete-length PEG (dPEG) chain is 16 atoms (18.3 Å) long. The sulfhydryl end of the crosslinker reacts with gold (forming dative bonds) and with thiol-reactive functional groups such as maleimide, bromoacetyl, SPDP, and thiol. The carboxylic acid end of the molecule couples to free amines using EDC or any suitable carbodiimide. An acylating agent such as N-hydroxysuccinimide (NHS) or 2,3,5,6-tetrafluorophenol (TFP) can enhance coupling efficiency. The carboxylate must react after the sulfhydryl conjugation.
