PEGylated Amino Acids - NEW


PEGylation has become a well-accepted method for the delivery of biopharmaceuticals-especially peptide and protein drugs.1-4 Simple modification of a drug with polyethylene glycol (PEG) not only is capable of improving the drug’s solubility, diminishing the potential for aggregation, and minimizing interference for both in vitro and in vivo applications, but is also able to protect it from proteolytic digestion, increasing its half-life in biological applications in the process.1-4 

AnaSpec is pleased to highlight our wide collection of Fmoc- and Boc-protected PEGylated amino acids for PEGylated peptides synthesis (Table 1). As well, custom synthesis of PEGylated peptides is available through our Fremont, California facilities. To obtain a price quotation, please click here or email service@anaspec.com.
