Its active site binds chloroalkane (CA)substrates, forming an irreversible covalent bond. This stable linkage between the HaloTag protein and its ligand enables rapid and efficient isolation and purification of tagged proteins. In this product, the chloro atom in Biotin PEG4 halo is replaced with a methyl group,
