Ligand Building Blocks can carry a variety of functionalities, including fluorescent labels, affinity tags and attachments to a solid phase. The covalent bond forms rapidly under general physiological conditions, is highly specific and essentially irreversible. The HaloTag Ligand Building Blocks allow researchers to apply the chloroalkane group that HaloTag protein reacts with to any compound or surface with a compatible chemical group, creating endless possible applications.
