  • Process for the production of proteins and the production of arrays of proteins
    Patent number: 7202055
    Abstract: Described is a novel process for the production of at least one protein of interest by secretion of the protein of interest from a pro- or eukaryotic host cell in a compartment system, which host cell is stably expressing a secretion system and capable of heterologous secretion of the protein of interest and which compartment system has at least a first and a second compartment and wherein the host cell is located in the first compartment and wherein the first and second compartment are separated from each other by a barrier, wherein the barrier is permeable for the secreted protein of interest, but not permeable for the host cell.
    Type: Grant
