Liberation thermique d'une proteine recombinante dans un milieu de culture

Thermal release of recombinant protein into culture media


The invention relates to a method for the isolation of a substantially pure polypeptide from a recombinant bacterial host by culturing the host under recombinant protein-producing conditions followed by heating the aqueous nutrient medium to 50-100°C for a time not to exceed 1 hour and recovering the substantially pure polypeptide so produced.
La présente invention se rapporte à un procédé pour l'isolation d'un polypeptide pratiquement pur contenu dans un hôte bactérien recombinant, par la culture dudit hôte dans des conditions de production d'une protéine recombinante, suivie du chauffage du milieu nutritif aqueux à une température de 50-100°C pendant une durée n'excédant pas une heure, puis de la récupération du polypeptide quasiment pur ainsi produit.
