Peptide-small molecule conjugates
Unique carbonyl/carboxyl reactive dibenzylcyclooctyne, which reacts with acids, active esters and aldehydes. The very hydrophilic PEG4 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. Due to its length, the 24 Å (20 atoms) long spacer gives ready accessibility to the dibenzylcyclooctyne for the azide binding.
Important Product Information
Do not use DTT, TCEP or β-mercaptoethanol, because they will reduce the azide.
Copper-free Click Reaction
Problem: Low conjugation of DBCO and azide
