Abstract
SE REFIERE A UN METODO EN EL CUAL UNA LINEA CELULAR DE MAMIFERO COMO UN MIELOMA, PARTICULARMENTE NSO QUE CONTIENE UNA SECUENCIA QUE CODIFICA UNA PROTEINA O POLIPEPTIDO RECOMBINANTE; ES ADAPTADA A CRECER EN UN MEDIO LIBRE DE SUERO Y PROTEINA, EL PROCEDIMIENTO COMPRENDE DOS ETAPAS: I) UNA ETAPA NO CRITICA EN LA CUAL A PARTIR DE UNA LINEA CON UNA VIABILIDAD CELULAR ENTRE 80% Y 100% LAS CELULAS CRECEN SUCESIVAMENTE EN MEDIO DE CULTIVO CON CONCENTRACIONES DECRECIENTES DE PROTEINA HASTA ALCANZARSE UNA CONCENTRACION CRITICA DE PROTEINA DONDE LA VIABILIDAD CAE A 0%; II) UNA ETAPA CRITICA EN EL CUAL UNA VEZ DETERMINADA LA CONCENTRACION CRITICA (ESTAS CONCENTRACIONES SON ESPECIFICAS PARA CADA LINEA CELULAR Y GENERALMENTE ESTAN POR DEBAJO DE 0,6 MG/ML) SE BUSCA LA CONCENTRACION ANTERIOR DONDE AUN EXISTE CRECIMIENTO CELULAR CONSIDERADA COMO CONCENTRACION PRE-CRITICA Y A PARTIR DE LA MISMA SE DISMINUYE LENTAMENTE DICHA CONCENTRACION DE PROTEINA HASTA QUE LAS CELULAS RECUPEREN SU VIABILIDAD Y EL TIEMPO DE DOBLAJE ORIGINAL. TAMBIEN SE INDICA QUE LAS LINEAS CELULARES QUE CRECEN ESTABLEMENTE EN ESTAS CONDICIONES DE MEDIO LIBRE DE SUERO Y PROTEINAS ES POR AL MENOS 40 GENERACIONES, ADICIONALMENTE LOS CLONES OBTENIDOS EXPRESAN LOS ANTICUERPOS ANTI RECEPTOR DE EGF hR3, EL ANTI CD6 T1hT HUMANIZADOS Y EL ANTICUERPO QUIMERICO ANTI CD3 T3Q ADEMAS DE LOS FRAGMENTOS DE DICHOS ANTICUERPOS
