PROBLEM TO BE SOLVED: To provide a composition and a method for recombinatorial cloning. SOLUTION: The composition includes vectors having multiple recombination sites and/or multiple topoisomerase recognition sites. The method permits the simultaneous cloning of two or more different nucleic acid molecules. In some embodiments, the molecules are fused together while in other embodiments the molecules are inserted into distinct sites in a vector. Also provided are the linking or joining through recombination of a certain number of molecules and/or compounds (e.g., chemical compounds, drugs, proteins or peptides, lipids, nucleic acids, carbohydrates, etc.) which may be the same or different, and a kit comprising host cells and nucleic acid molecules.

Abstract:
PROBLEM TO BE SOLVED: To provide system and method for acoustic focusing hardware and implementations.SOLUTION: An acoustic focusing capillary tube includes a capillary tube coupled to at least one vibration supply source having a groove. A method for manufacturing the acoustic focusing capillary tube includes steps of: providing the capillary tube, and the at least one vibration supply source; performing machine work of the groove in the vibration supply source; and connecting the at least one vibration supply source to the capillary tube in the groove. Another method includes steps of: pouring sheath fluid into an outside area of the capillary tube; pouring particle flow into the center core of the capillary tube; and acoustically focusing particles of the particle flow by applying acoustic radiation pressure to the particle flow at a first position along the capillary tube regarding focusing of the particle flow. The particle flow can be further focused by being hydrodynamically focused at a second position along the capillary tube downstream of the first position.
Abstract:
PROBLEM TO BE SOLVED: To provide a method and an apparatus relating to a large scale FET for measuring an analyte.SOLUTION: ChemFET (e.g., ISFET) arrays may be manufactured by using conventional CMOS processing technique based on an improved FET pixel and array design that increase measurement sensitivity and accuracy, and at the same time facilitate significantly small pixel size and high-density arrays. Such arrays may be employed to detect presence and/or concentration change of an analyte of various types in a variety of chemical and/or biological processes. In one example, the chemFET arrays facilitate DNA sequencing technique based on monitoring change in hydrogen ion concentration (pH), change in other analyte concentration, and/or binding events associated with the chemical processes relating to DNA synthesis.
Abstract:
PROBLEM TO BE SOLVED: To provide methods of remodeling and labeling proteins and antibodies at novel oligosaccharide linkages; and to provide antibodies or proteins linked to modified oligosaccharides.SOLUTION: A step of attaching a modified sugar-containing chemical handle to a GlcNAc residue on a first protein, and a step of mixing the first protein with a reporter molecule, carrier molecule or solid support capable of reacting with the chemical handle are included. The reporter molecule, carrier molecule or solid support attaches to the protein at the chemical handle, thereby forming the glycomodified protein. The first protein is an antibody.
Abstract:
PROBLEM TO BE SOLVED: To provide a system and method for accurately and effectively identifying individual bases of DNA or RNA.SOLUTION: This field effect transistor (FET), nucleic acid sequencing device (102) comprises source (106) and drain (104) regions, and gate oxide (136). Potential is applied to the source and drain by voltage source (112) through leads (116) connected to the source/drain metal contacts (123, 142). As nucleic acid strand (111) passes through an opening (118) which serves as the gate electrode region, the charge representative of a nucleic acid base (adenine, thymine, guanine or cytosine) modifies the current flowing between source (106) and drain (104) via a channel (119) by modifying the electric field therebetween and is measured by ammeter (114).

PROBLEM TO BE SOLVED: To provide powder nutritive culture medium, culture medium supplements, culture medium subgroup formulations.SOLUTION: The present invention provides cell culture medium supplements (including powdered sera such as powdered fetal bovine serum (FBS)), culture medium subgroup formulations, and cell culture media comprising all of the necessary nutritive factors including a lipid component that facilitates the in vitro cultivation of cells. The dry powder nutritive culture medium, the culture medium supplements, the culture medium subgroup, and buffer formulations are used for cultivation of prokaryotic and eukaryotic cells, particularly bacterial cells, yeast cells, plant cells, and animal cells (including human cells). Prior to this, aseptic powder culture medium, the culture medium supplements (particularly powdered sera such as powdered FBS, powdered transferrin, powdered insulin, powdered organ extracts (bovine brain or bovine pituitary extracts, etc.), powdered growth factor (EGF, FGF, etc.), etc.) the culture medium subgroup, and the buffer formulations are produced, antisepsis is achieved with γ-irradiation, and the culture medium, supplements, culture media subgroups, and buffer formulations are powdered.
Abstract:
PROBLEM TO BE SOLVED: To provide cationic lipids and compositions of the cationic lipids having utility in lipid aggregates for delivery of macromolecules and other materials into cells. SOLUTION: There are provided compounds expressed by general structural formula. The compounds are useful either in a single form or in combination with other lipid aggregate-forming components (e.g., DOPE, DOPC or cholesterol) for formulation into liposomes or other lipid aggregates. The aggregates are polycationic and are able to form stable complexes with anionic macromolecules such as nucleic acids. The lipid aggregate polymer complexes interact with cells having polyanionic marcromolecules for absorption and intake by the cells. COPYRIGHT: (C)2011,JPO&INPIT
