特点和优势

MAL-dPEG®8-TFP ester is a heterobifunctional, linear crosslinking reagent containing a maleimide group on one end of the single molecular weight dPEG® spacer arm and an amine-reactive active ester on the other end. The maleimide group reacts readily and specifically with free sulfhydryl groups in aqueous media at pH 6.5-7.5. The 2,3,5,6-tetrafluorophenyl (TFP) ester is used widely in reactions with primary amines. The TFP-amine reactions can be carried out in aqueous or organic solvent. The dPEG® spacer is hydrophilic and non-immunogenic. Because it is a single molecular weight product, it gives the user precise spatial control. The dPEG® spacer also improves water solubility, decreases immunogenicity, and increases the hydrodynamic volume of the conjugate. The increased hydrodynamic volume results in longer serum half-life in vivo.
