The HaloTag® Fluorescent Ligands 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® Fluorescent Ligands 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.
HaloTag® Ligands for Protein Detection The HaloTag® Biotin Ligand consists of a 12-atom linker arm to biotin and is used as an affinity tag to capture the HaloTag® protein-based fusion construct using the strong biotin-streptavidin interaction.
