Features and Benefits
Thiol-dPEG12-acid is a single molecular weight, discrete-length polyethylene glycol (dPEG) crosslinking PEGylation reagent. One end of the crosslinker terminates in a sulfhydryl (thiol) group. Propionic acid terminates the opposite end. The thiol end of the molecule forms dative bonds with gold. Moreover, it forms thioether bonds with maleimide and bromoacetate groups and disulfide bonds with other sulfhydryl groups. The propionic acid group reacts with amines to form amide bonds. Alternatively, if it is left unreacted, the propionic acid group provides a negative charge to the conjugated molecule or modified surface. The monodispersed dPEG spacer is 39 atoms (46.8 Å) long.
