The HaloTag Iodoacetamide (O2) Ligand contains a reactive iodoacetamide group connected to an alkylchloride separated by an ethylene glycol repeat (O2). HaloTag Iodoacetamide (O2) Ligand has been designed to rapidly react with sulfhydryl-containing molecules (see figure), whether small organic compounds, peptides or proteins. The ligand with functional group can then be used with the HaloTag protein for any application of interest.
