Zusammenfassung:As antibody variants and isoforms having reduced FVIII mimetic activity than Emicizumab, the antibody variants having some specific amino acid residues in the variable region cleaved out and missing (Q-CDR-Clipped Variants) and the antibody isoforms having inter-heavy chain disulfide bonds less susceptible to reduction under mild reducing conditions (Protected Disulfide Isoforms) are provided.
