|20130143264||HIGH EFFICIENCY GENE TRANSFER AND EXPRESSION IN MAMMALIAN CELLS BY AMULTIPLE TRANSFECTION PROCEDURE OF MAR SEQUENCES - The present invention relates to purified and isolated DNA sequences having protein production increasing activity and more specifically to the use of matrix attachment regions (MARs) for increasing protein production activity in a eukaryotic cell. Also disclosed is a method for the identification of said active regions, in particular MAR nucleotide sequences, and the use of these characterized active MAR sequences in a new multiple transfection method.||06-06-2013|
|20120231449||PRODUCTS AND METHODS FOR ENHANCED TRANSGENE EXPRESSION AND PROCESSING - Disclosed are methods and eukaryotic host cells for transgene expression. The cells may be treated and/or modified to increase homologous recombination (HR), decrease non homologous end joining (NHEJ) and/or to enhance a HR/NHEJ ratio in said cell. Such cells can be transfected with vectors comprising the transgene, which advantageously integrates into the genome of the cell to form a concatemeric structure which may comprise more than 200 transgene copies. Certain expression enhancing elements such as MARs are advantageously provided to further enhance and/or facilitate transgene expression. Disclosed is also a recombinant eukaryotic host cell, in particular a non-primate host cell, comprising a transgenic sequence encoding a protein and/or a RNA, in particular a primate protein and/or RNA, involved in translocation across the ER membrane and/or secretion across the cytoplasmic membrane.||09-13-2012|
|20110061117||MATRIX ATTACHMENT REGIONS (MARS) FOR INCREASING TRANSCRIPTION AND USES THEREOF - Isolated and purified MAR sequences of human and non-human animal origin are disclosed as are nucleotide sequences corresponding to or based on them. In particular, MARs and MAR constructs with high transcription and/or protein production enhancing activities are disclosed and so are methods for identifying such MARs, designing such MAR constructs and employing them, e.g., for high yield production of proteins.||03-10-2011|
