The HaloTag® Technology platform addresses the need for flexibility in functional protein analysis. This modular technology is based on the formation of a covalent bond between a fusion tag, HaloTag® reporter protein, and synthetic ligands, and enables complete characterization of protein function in cellular and biochemical environments. There are a variety of HaloTag® Ligands and kits available for fluorescent cell imaging and protein capture/purification, as well as reactive customizable Ligand Building Blocks. The ligands described are soluble in cell media or aqueous buffers.

The modular nature of HaloTag® technology and the rapid binding kinetics with its ligands can directly image both protein trafficking and turnover. The available ligands have both varied fluorescent spectra and also cell-permeant and impermeant properties to provide spatial and temporal control. For example, you can label only the surface pool of a membrane-bound protein with a cell-impermeant ligand and follow its biology, internalization or other fate. Or a protein can first be labeled with a ligand that has one dye color, and after a period of time labeled again with a ligand containing a dye of a different color. Such pulse-chase labeling allows direct observation of protein trafficking and/or turnover over time.
