• GlycoPEGylation attaches PEG at a site remote from the active site, thereby preserving activity while extending half-life
• GlycoPEGylation is a mild, enzymatic process
• GlycoPEGylation may be successful where traditional chemical pegylation has failed
• GlycoPEGylation is customizable--the amount and molecular weight of PEG, as well as the number of attachment sites, can be controlled to achieve specific results
