The invention provides a method for identifying positions of an antibody that can be modified without significantly reducing the binding activity of the antibody. In many embodiments, the method involves identifying a substitutable position in a parent antibody by comparing its amino acid sequence to the amino acid sequences of a number of related antibodies that each bind to the same antigen as the parent antibody. The amino acid at the substitutable position may be substituted for a different amino acid without significantly affecting the activity of the antibody. The subject methods may be employed to change the amino acid sequence of a CDR without significantly reducing the affinity of the antibody of the antibody, in humanization methods, or in other antibody engineering methods. The invention finds use in a variety of therapeutic, diagnostic and research applications.

L'invention concerne une méthode pour identifier des positions d'un anticorps pouvant être modifiées sans réduction significative de l'activité de liaison de l'anticorps. Dans plusieurs modes de réalisation de l'invention, la méthode consiste à identifier une position de substitution dans un anticorps parent, par la comparaison de sa séquence d'acides aminés aux séquences d'acides aminés d'un certain nombre d'anticorps associés se liant chacun au même antigène que l'anticorps parent. Un acide aminé situé à la position de substitution peut être substitué par un acide aminé différent sans modifier de manière significative l'activité de l'anticorps. Les méthodes de l'invention peuvent être employées pour changer la séquence d'acides aminés d'un CDR sans réduire de manière significative l'affinité de l'anticorps, dans des méthodes d'humanisation, ou dans d'autres méthodes d'ingénierie d'anticorps. L'invention peut être utilisée dans une variété d'applications thérapeutiques, diagnostiques et de recherche.
