A bispecific antibody substituting for a ligand for a I type interferon receptor comprising two types of molecules having AR1 and AR2 chains is successfully isolated. Further, a bispecific antibody binding to both of blood coagulation factor IX/activated blood coagulation factor IX and blood coagulation factor X and substituting for the function of blood coagulation factor VIII/activated blood coagulation factor VIII enhancing an enzyme reaction is successfully constructed. |
