Abstract

La memoria descriptiva describe una composición que comprende un medio mejorado de cultivo de células eucarióticas, la cual se puede utilizar para la producción de una proteína de interés. Se puede agregar taurina al medio libre de suero o al medio químicamente definido para aumentar la producción de una proteína de interés. Se incluyen métodos para expresar recombinantemente niveles elevados de proteína utilizando las composiciones que comprenden el medio. Reivindicación 1: Un método para cultivar células eucarióticas recombinantes para la producción mejorada de dupilumab, caracterizado porque comprende las etapas de: (a) propagar las células eucarióticas recombinantes en un medio de cultivo celular definido durante una fase de crecimiento, donde dicho medio de cultivo celular está libre de glutamina; (b) suplementar el medio de cultivo celular definido con aproximadamente 0,1 mM a aproximadamente 10 mM de L-taurina y uno o más de los siguientes: 0 mM a 11,2 mM de alanina, 2,4 mM a 11,9 mM de arginina, 1,3 mM a 33,3 mM de asparagina, 1,5 mM a 93,9 mM de ácido aspártico, 1,1 mM a 19,9 mM de cisteína, 1,4 mM a 47,6 mM de ácido glutámico, 0 mM a 16,7 mM de glicina, 1 mM a 9,5 mM de histidina, 1,5 mM a 22,9 mM de isoleucina, 1,5 mM a 38,1 mM de leucina, 2,7 mM a 24,6 mM de lisina, 1,3 mM a 13,4 mM de metionina, 1,2 mM a 18,2 mM de fenilalanina, 1,7 mM a 26,1 mM de prolina, 1,9 mM a 57,1 mM de serina, 1,7 mM a 33,6 mM de treonina, 0,5 mM a 14,7 mM de triptofano, 0,9 mM a 22,2 mM de tirosina, y 1,7 mM a 34,1 mM de valina; y (c) expresar dupilumab durante la fase de producción, donde la adición de L-taurina incrementa el título de dupilumab en al menos 3% comparado con células que expresan dupilumab en un medio de cultivo celular que contiene menos de 0,1 mM de L-taurina. Reivindicación 13: Un método para cultivar células eucarióticas recombinantes para la producción mejorada de dupilumab, caracterizado porque comprende las etapas de: (a) propagar las células en un medio de cultivo celular definido durante una fase de crecimiento, y (b) suplementar el medio de cultivo celular definido con aproximadamente 0,1 mM a aproximadamente 10 mM de L-taurina, y expresar dupilumab durante la fase de producción, donde la adición de L-taurina incrementa el título de dupilumab en al menos 7% comparado con células que expresan dupilumab en un medio de cultivo celular que contiene menos de 0,1 mM de L-taurina, y donde dicha propagación de las células durante dicha fase de crecimiento se lleva a cabo a una temperatura de aproximadamente 35ºC a 38ºC, y dicha expresión de dupilumab durante dicha fase de producción se lleva a cabo a una temperatura de aproximadamente 29ºC a 37ºC, donde la temperatura de dicha fase de crecimiento es mayor que la temperatura de dicha fase de producción. Reivindicación 19: Un método para producir dupilumab caracterizado porque comprende las etapas de: (a) cultivar células que expresan dupilumab en un medio de cultivo celular que comprende de aproximadamente 0,1 mM a aproximadamente 10 mM de L-taurina, donde la adición de L-taurina incrementa el título de dupilumab en al menos un 3% a un 7% en comparación con las células que expresan dupilumab en un medio de cultivo celular que contiene menos de 0,1 mM de L-taurina; y (b) producir dupilumab en la célula, donde el dupilumab se secreta al medio, donde dichas células se cultivan a una temperatura de aproximadamente 35ºC a 38ºC durante una fase de crecimiento y aproximadamente 29ºC a 37ºC durante una fase de producción, donde la temperatura de la fase de crecimiento es mayor que la temperatura de la fase de producción. Reivindicación 23: Un método para producir dupilumab caracterizado porque comprende cultivar una línea celular recombinante en un medio de cultivo celular que comprende al menos aproximadamente 0,1 mM de L-taurina, donde la línea celular recombinante comprende un ácido nucleico integrado en forma estable que codifica dupilumab, y producir dupilumab a partir de las células, donde la adición de L-taurina al medio de cultivo celular incrementa el título del dupilumab en al menos 3% a 7% en comparación con cultivar la línea celular recombinante en un medio de cultivo celular que contiene menos de 0,1 mM de L-taurina; y donde dicha línea celular recombinante se cultiva a una temperatura de aproximadamente 35ºC a 38ºC durante una fase de crecimiento y aproximadamente 29ºC a 37ºC durante una fase de producción, donde la temperatura de la fase de crecimiento es mayor que la temperatura de la fase de producción.
