Abstract:
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.
Abstract:
The present invention relates to a peptide able to specifically bind a chemokine receptor consisting essentially in the sequence NPFYYLSFSP, or LLXXXFFXXX, a part thereof, a combination thereof and/or variants. Furthermore, it relates to a pharmaceutical composition comprising as an active substance a pharmaceutically effective amount of at least one of said peptide.
Abstract:
A method for separating target molecules or particles from a fibrinogen containing sample comprises: (a) trapping the said target molecules or particles in a fibrin network by converting at least partially the fibrinogen contained in the sample into fibrin; (b) retracting the said fibrin network to form a fibrin clot; (c) separating the said fibrin clot from the surrounding sample medium,

Abstract:
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 enhanced 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 strucutre 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 particualr a primate protein and/or RNA, involved in translocation across the ER membrane and/or secretion across the cytoplasmic membrane.

Abstract:
The invention concerns a new family of proteins obtained from Moringa seeds or derived from Moringa seed proteins. Those proteins can be used for different purposes such as coagulation agents for the water treatment and/or as antibiotic agents.This new protein family consists of at least 5 sub-families :A first being obtained according to a recombinant process. All other sub-families being obtained according to specific extraction processes. Proteins obtained according to the extraction process of the invention will be referred as E proteins in the present text.
Abstract:
The present invention relates to compositions and method for transfecting eukaryotic cells with nucleic acid vectors. In particular, the invention relates to uses of MAR elements to increase stable and transient transfection efficiency.
