特点和优势
MAL-dPEG?4-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 number following the dPEG?refers to the exact number of spacer units present in the spacer arm. 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.
