Abstract

Procedimiento de selección de un linfocito B que comprende las etapas siguientes: a) cocultivar cada uno de los linfocitos B de una población de linfocitos B, que se ha depositado como célula simple, con células EL-4 B5 murinas como células alimentadoras, b) seleccionar un clon de linfocitos B que haga proliferar y segregue anticuerpo en la etapa a), en la que el cocultivo es en presencia de una mezcla alimentadora sintética que comprende IL-1β, TNFα, IL-10, y uno o más seleccionados de IL-21, SAC, BAFF, IL-2, IL-4 e IL-6.
