Abstract

En la presente se reporta un método para la generación de anticuerpos multiespecíficos directamente en la superficie celular en el sitio de acción mediante una reacción de intercambio de mitades de anticuerpos entre dos 2/3-IgG o dos 2/3-BiFab desestabilizadas por la mitad mediante mutaciones perturbadoras asimétricas que fomentan la generación de anticuerpos biespecíficos o multiespecíficos de longitud completa correctamente ensamblados. El método se realiza en la ausencia de enlaces de disulfuro de región bisagra en las 2/3-IgG o 2/3-BiFab iniciales.
