Nemolizumab (Genetical Recombination)



Nemolizumab is a recombinant humanized monoclonal antibody composed of complementarity-determining regions derived from mouse anti-human interleukin-31 receptor antibody, human framework regions and human IgG2 constant regions. In the H-chain, amino acid residues at position 135, 137, 141, 142, 223, 268, 355 and 419 are substituted by Ser, Lys, Gly, Gly, Ser, Gln, Gln and Glu, respectively, and Gly and Lys at the C-terminus are deleted. Nemolizumab is produced in Chinese hamster ovary cells. Nemolizumab is a glycoprotein (molecular weight: ca. 147,000) composed of 2 H-chains (γ2-chains) consisting of 445 amino acid residues each and 2 L-chains (κ-chains) consisting of 214 amino acid residues each.
