WebDescription: Unique carbonyl/carboxyl reactive dibenzylcyclooctyne, which reacts with acids, active esters and aldehydes. The very hydrophilic PEG 4 spacer enhances solubility in water as well as in commonly used organic solvents of moderate polarity. Furthermore, the very water soluble, hydrophilic spacer reduces non-specific binding. WebThe reaction can be run either in organic solvent or in aqueous buffer depending on the solubility and property of substrate molecules. The PEG space of the reagent increases the hydrophilicity and fine-tunes the properties of the PEGylated molecules.
