HaloTag is a self-labeling protein derived from the haloalkane dehalogenase DhaA from Rhodococcus rhodochrous

ensuring stable labeling for long-term tracking

Negative Control of Biotin-PEG4-CA acid 79 SMILES: CC1(C)\C(=C/C=C/C2=[N+](CCCCCC(=O)OCC#C)C3=CC=CC=C3C2(C)C)N(CCCS([O-])(=O)=O)C2=CC=CC=C12 Purity (HPLC):HaloTag is a self labeling protein tag engineered from the haloalkane dehalogenase DhaA, originally isolated from Rhodococcus rhodochrous. 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,
