Daclizumab [USAN:INN:BAN]; Daclizumab; Humanized anti-TAC monoclonal antibody comprised of four subunits, two heavy chains and two light chains. All four chains are linked via disulfide bridges. The molecule contains approximately 2% carbohydrate by weight. The antibody belongs to the IgG1 subclass. The DNA sequence is 90% human origin and 10% mouse origin. The humanized anti-TAC is directed to the TAC receptor or high-affinity interleukin 2 receptor. Immunoglobulin G 1 (human-mouse monoclonal clone 1H4 gamma-chain anti-human interleukin 2 receptor), disulfide with human-mouse monoclonal clone 1H4 light chain, dimer. Molecular weight is approximately 150,000 daltons; Immunoglobulin G 1 (human-mouse monoclonal clone 1H4 gamma-chain anti-human interleukin 2 receptor), disulfide with human-mouse monoclonal clone 1H4 light chain, dimer; Ro 24-7375; UNII-CUJ2MVI71Y; Zenapax
