Abstract

Método de obtención de células de mamífero adaptadas a crecer en medio libre de suero y proteínas, el procedimiento incluye un proceso en dos etapas de adaptación para crecer en esa condición. Se revela la existencia de un intervalo crítico de concentración de proteína en el cual las células deben crecer para ganar la capacidad de sobrevivir en medio libre de proteínas, una vez que las células hayan crecido en las concentraciones críticas del intervalo, las disminuciones subsiguientes de la concentración no afectan la viabilidad ni el tiempo de doblaje celular. El intervalo crítico de la concentración de la proteína es específico para cada línea celular. Líneas celulares de mamíferos que crecen establemente en condiciones de medio libre de suero y proteínas por al menos 40 generaciones. Adicionalmente, los clones revelados, expresan un producto recombinante. Los clones expresan los anticuerpos anti receptor de EGF hR3, el anti CD6 T1hT humanizados y el anticuerpo quimérico anti CD3 T3Q, además de los fragmentos de dichos anticuerpos. Reivindicación 1: Un método para obtener una línea celular de mamífero adaptada a crecer en medio libre de suero y proteína que comprende dos etapas: I) Una primera etapa en la cual a partir de una línea con una viabilidad celular entre 80 y 100%, las células se crecen sucesivamente en medio de cultivo con concentraciones decrecientes de proteína hasta alcanzarse una concentración crítica de proteína donde la viabilidad cae a 0%; II) Una segunda etapa donde una vez determinada la concentración crítica, se busca la concentración precedente, donde aún existe crecimiento celular considerada como concentración pre-crítica, y a partir de la misma se disminuye lentamente dicha concentración de proteína hasta que las células recuperen la viabilidad y el tiempo de doblaje original.
