설명

특징 및 장점

MAL-dPEG^® ₂₄-NHS ester is a heterobifunctional, linear crosslinking reagents 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. N-hydroxysuccinimide (NHS) ester are used widely in reactions with primary amines. The NHS-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.
