Title (EN) ANTIBODY HAVING ENHANCED ACTIVITY, AND METHOD FOR MODIFYING SAME
(FR) ANTICORPS PRÉSENTANT UNE ACTIVITÉ ACCRUE ET SON PROCÉDÉ DE MODIFICATION
(JA) 増強された活性を有する抗体及びその改変方法
Abstract:
(EN) As a result of producing an ACE910 variant obtained by modifying various sites in a constant region, a bispecific antibody having FVIII-like activity, which is higher than that of ACE910, has been discovered. Furthermore, a method for identifying the positions of mutations that enhance FVIII-like activity and enhancing FVIII-like activity using said mutations has been discovered.
(FR) Dans le cadre de la présente invention, suite à la production d'une variante ACE910 obtenue en modifiant divers sites dans une région constante, un anticorps bispécifique ayant une activité de type FVIII qui est supérieure à celle d'ACE910 a été découvert. L'invention concerne également un procédé pour identifier les positions des mutations qui améliorent l'activité de type FVIII et pour améliorer l'activité de type FVIII en utilisant ces mutations.
(JA) 定常領域の様々な部位を改変したACE910変異体を作製した結果、ACE910よりも高いFVIII様活性を有する二重特異性抗体を見出した。また、FVIII様活性を高める変異位置の同定、その変異を用いたFVIII様活性を高める方法を見出した。
