    摘要: By altering amino acid sequences, the present inventors successfully produced constant regions that can confer antibodies with particularly favorable properties for pharmaceutical agents. When used to produce antibodies, the altered constant regions produced according to the present invention significantly reduce heterogeneity. Specifically, the antibody homogeneity can be achieved by using antibody heavy chain and light chain constant regions introduced with alterations provided by the present invention. More specifically, the alterations can prevent the loss of homogeneity of antibody molecules due to disulfide bond differences in the heavy chain. Furthermore, in a preferred embodiment, the present invention can improve antibody pharmacokinetics as well as prevent the loss of homogeneity due to C-terminal deletion in antibody constant region.

    摘要: By altering amino acid sequence, the present inventors succeeded in providing constant regions that can confer antibodies with favorable properties, particularly as pharmaceuticals. The variants of the constant regions provided by the present invention will remarkably reduce heterogeneity when applied to antibody production. That is, homogeneity of antibodies can be maintained at a high level by introducing the alterations provided by the present invention into the antibody heavy chain constant regions. More specifically, decrease in homogeneity caused by —SS— bond linkage differences in the heavy chains of antibody molecules can be prevented. Furthermore, in a preferred embodiment of the present invention, pharmacokinetics of antibodies can be improved and decrease in homogeneity caused by deletion of the C terminus in the antibody constant region can be ameliorated.
