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. CA Cy5 is a HaloTag ligand with Cyanine5 dye. Cy5 (Cyanine 5, 649Ex 710Em) dyes are
