HaloTag® technology is a powerful tool for functional protein analysis based on the formation of a covalent bond between the HaloTag® protein fusion tag and synthetic chemical ligands. By interchanging ligands, you can control the function and properties of the HaloTag® fusion protein, allowing use of the same construct for protein purification, protein interaction analysis, and cell-based assays for protein translocation, receptor internalization, and protein stability studies.
Available HaloTag® ligands include magnetic and non-magnetic beads, glass slides, cell-permeable and impermeable fluorescent ligands, biotin, and reactive ligands that allow you to build your own custom HaloTag® ligands and surfaces.
Efficiently capture proteins expressed in E. coli as HaloTag® fusions.
Purify fusion proteins directly from mammalian cell culture lysates, even at low expression levels.
Perform multicolor live- and fixed-cell imaging experiments using a single genetic construct.
Capture and purify intracellular binary and higher order protein complexes, including transient or weakly interacting partners.
Capture intracellular protein:DNA complexes without using antibodies.
Choose from an extensive library of prebuilt HaloTag® human ORF clones.
