    摘要: The invention concerns the field of protein production and cell culture technology. It describes a method of producing a heterologous protein of interest in a cell comprising a. Increasing the expression or activity of a secretion enhancing gene, and b. Increasing the expression or activity of an anti-apoptotic gene, and c. Effecting the expression of said protein of interest, whereby the secretion enhancing gene is a gene encoding a protein whose expression or activity is induced during one of the following cellular processes: plasma-cell differentiation, unfolded protein response (UPR), endoplasmic reticulum overload response (EOR).

    摘要: The present invention refers to the area of cell culture technology and relates to methods for multiplying/cloning cells, preferably cell lines, which are important to the production of biopharmaceuticals. The invention further relates to methods for manufacturing proteins and to the use of cells extracted and multiplied through single cell sorting and to media compositions that enable a multiplication of single cells. Through the use of albumin-producing, preferably HSA-producing, cells as feeder cells for the conditioning of medium or as host cells, the recloning efficiency and thereby the quantity of clones obtained can be significantly increased. A combination of these approaches is also possible. Through the use of albumin-producing, preferably HSA-producing, cells, an increase in the recloning efficiency can be achieved in serum-free and/or insulin-free medium as well, and in different cell types.

    摘要: The invention concerns the field of cell culture technology. The invention describes production host cell lines comprising vector constructs comprising a CERT S132 A expression cassette. Those cell lines have improved growth characteristics and high CERT S132A expression levels. The invention especially concerns two cell lines deposited with the DSMZ under the number DSM ACC2989 (CHO/CERT 2.20) and DSM AC-C2990 (CHO/CERT 2.41). The invention further concerns a method of generating such preferred production host cells and a method of producing proteins using the two cell lines deposited with the DSMZ under the number DSM ACC2989 (CHO/CERT 2.20) and DSM ACC2990 (CHO/CERT 2.41).

    摘要: The invention concerns the field of cell culture technology. The invention describes production host cell lines comprising vector constructs comprising a DHFR expression cassette. Those cell lines have improved growth characteristics in comparison to DHFR-deficient or DHFR-reduced cell lines such as CHO DG44 and CHO DUKX-B11. The invention especially concerns two cell lines, a representative of each cell line is deposited with the DSMZ under the number DSM ACC2909 (CHOpper® Discovery) and DSM ACC2910 (CHOpper® Standard). The invention further concerns a method of producing proteins using the cells generated by the described method.
