Outline of Final Research Achievements |
The covalent attachment of poly(ethylene glycol) (PEG) with an average molecular weight (Mw) of 5-40 kDa to a drug or a therapeutic protein, called PEGylation, is a common strategy to evade the host immune system, to enhance its stability in blood, etc. In this study, we have developed a synthetic method of PEGylated peptides, possessing a fluorescent moiety at one end of the PEG chain, which enabled noninvasive whole-body trafficking of such molecules in living rats.
