Title (EN) METHOD FOR DETERMINING THE IN VIVO INTERACTION MODE
(FR) PROCÉDÉ DE DÉTERMINATION DU MODE D'INTERACTION IN VIVO
Abstract:
(EN) Herein is reported a method for determining the binding interaction with a multimeric antigen of an antibody of the human IgG1 subclass that has at least two binding sites specifically binding to the antigen comprising the steps of 1) determining the binding affinity of the antibody for the multimeric antigen, and 2) incubating a mixture comprising the antibody and a polypeptide that is derived from lysine-gingipain of porphyromonas gingivalis under conditions and for a time sufficient to cleave the antibody into Fabs and Fc-region, and determining the binding affinity of the Fabs of the antibody for the multimeric, whereby the binding affinity of the antibody to the multimeric antigen to be affinity-driven if the binding affinity determined in both steps are comparable and to be avidity-driven if the binding affinity determined in both steps are different.
(FR) L'invention concerne un procédé visant à déterminer l'interaction de liaison avec un antigène multimère d'un anticorps de la sous-classe IgG 1 humaine qui présente au moins deux sites de liaison se liant spécifiquement à l'antigène. Ledit procédé comprend les étapes consistant : 1) à déterminer l'affinité de liaison de l'anticorps pour l'antigène multimère et 2) à incuber un mélange comprenant l'anticorps et un polypeptide dérivé de la lysine-gingipaïne de Porphyromonas gingivalis dans des conditions et pendant une durée suffisantes pour cliver l'anticorps en fragments Fab et Fc, puis à déterminer l'affinité de liaison des fragments Fab de l'anticorps pour l'antigène multimère, l'affinité de liaison de l'anticorps pour l'antigène multimère étant régie par l'affinité si les affinités de liaison déterminées lors des deux étapes sont comparables et par l'avidité si les affinités de liaison déterminées lors des deux étapes sont différentes.
