摘要:
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.

An introducer and method for delivering a prosthetic fabric into a patient. The introducer includes a delivery tube having a distal end adapted to be inserted into the patient and a lumen that receives the prosthetic fabric. A loader may be provided to reconfigure the prosthetic fabric from a first configuration to a collapsed configuration and/or to insert the collapsed fabric into the lumen of the delivery tube. A plunger may be provided to push the prosthetic fabric through the delivery tube and into the patient. The loader and plunger may be combined in a dual-purpose component that is reversible to either load the fabric into the delivery tube or push the fabric through the delivery tube.

摘要:
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.
摘要:
Altering properties of rendered objects and/or mixed reality environments utilizing control points associated with the rendered objects and/or mixed reality environments is described. Techniques described can include detecting a gesture performed by or in association with a control object. Based at least in part on detecting the gesture, techniques described can identify a target control point that is associated with a rendered object and/or a mixed reality environment. As the control object moves within the mixed reality environment, the target control point can track the movement of the control object. Based at least in part on the movement of the control object, a property of the rendered object and/or the mixed reality environment can be altered. A rendering of the rendered object and/or the mixed reality environment can be modified to reflect any alterations to the property.

摘要:
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.
