Azide-PEG-Tos

Azide-PEG-Tos reagent is a chemical reagent used in the synthesis of peptide and protein conjugates. It consists of a polyethylene glycol (PEG) spacer and a terminal azide group appended with a tosyl group for stabilization. This reagent is used for the synthesis of peptides, proteins and other biomolecules that can be labeled with various fluorophores, enzymes or other molecules of interest. The tosyl group can be removed after conjugation, allowing for further modification of the labeled molecule.
