Introduction

Dde Biotin-PEG4-DBCO is used for modifying proteins or surfaces such as beads, nanoparticles and self-assembled monolayers. Modification of proteins adds polyethylene glycol (PEG)_n spacers, which impart increased water solubility, reduced immunogenicity of the labeled molecule and enhanced in vivo stability in solution. Functionalization of solid surfaces, such as quantum dots, self-assembled monolayers and nanoparticles, with polyethylene glycol spacers significantly reduces nonspecific protein binding. 

Important Product Information

? The Amino-PEG8-Amine is low-melting solids that are difficult to weigh and dispense.
