mPEG-NHS Ester

The mPEGn-OCH₂CH₂COONHS Ester series, featuring mPEG11-OCH₂CH₂COONHS Ester as a representative product, is designed for efficient amine-reactive bioconjugation under mild conditions.  These reagents enable stable PEGylation of proteins, peptides, and nanoparticles, significantly improving solubility and reducing immunogenicity.  Key advantages include high reactivity, an extended spacer arm for enhanced binding accessibility, and customizable PEG chain length (n).  Due to the susceptibility of NHS esters to hydrolysis, anhydrous handling is recommended for optimal results.
