Abstract
La actual invención se relaciona con un método de obtención de células de mamífero adaptadas a crecer en medio libre de suero y proteínas, el procedimiento incluyen un proceso en dos etapas de adaptación para crecer en esa condición. La actual invención revela la existencia de un intervalo crítico de concentración de proteína en el cual las células deban 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 afecten la viabilidad ni el tiempo de doblaje celular. El intervalo crítico de la concentración de la proteína es específico para cada línea celular.La presente invención también revela 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 en la presente invención expresan un producto recombinante.Los clones de la presente invención 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.
