HaloTag® technology is a comprehensive platform for functional protein analysis based on the formation of a covalent bond between a protein fusion tag (HaloTag) and synthetic chemical ligands. By using different ligands you can control the function and properties of the HaloTag® fusion protein. The HaloTag® system gives exceptional performance in cell-based and biochemical assays without the need to switch fusion tags or reclone inserts.
In addition to the HaloTag® Vectors and Ligands available as catalog items, we offer a selection of pre-built custom HaloTag® vectors and ligands developed by our Custom Assay Services team within R&D. Although functionally tested, they are not manufactured under the Promega ISO13485 quality system and are sold “as is” with no warranty either stated or implied.
