CA-SiR Size:20nmol 177 SMILES [2H]C([2H])([2H])N1CCN(CC1)C1=CC=C(Br)C=C1 Purity (HPLC)HaloTag is a self labeling protein derived from the haloalkane dehalogenase DhaA from Rhodococcus rhodochrous. Its active site reacts with chloroalkane substrates to form an irreversible bond. The covalent linkage between the HaloTag ligand and HaloTag protein enables rapid isolation and purification. CA SiR is a fluorescent HaloTag fluorescent ligand. SiR (SiR 6 COOH, 652Ex 674Em) is a far red fluorescent dye that is bright, photostable, and cell
