HaloTag® Technology: A Powerful Tool for Protein Labeling and Analysis
Start by adding the HaloTag® protein fusion tag to your protein, pair the fusion protein with one of many interchangeable ligands that forms a highly specific covalent bond with HaloTag, and you open a gateway to investigate protein function. Once your protein of interest is fused to the HaloTag® protein, you are ready for numerous applications including protein purification, protein:protein or protein:DNA interactions, cellular imaging, receptor internalization and more. Each possible analysis pathway is based on which interchangeable HaloTag® ligand you select, or customize a ligand for your specific requirements.
