Abstract:
An insect control sheet containing a Cry polyhedron prepared by fixing an insecticidal protein (a Cry toxin) produced by Bacillus thuringiensis to a polyhedron of polyhedrin protein is provided. The insect control sheet contains the Cry polyhedron and is used by floating on water. The insect control sheet is floatable on water, and includes a pure matrix layer 20 and a toxin-containing matrix layer 30 containing the Cry polyhedron 51 which are layered on the underside of a sheet-shaped first sheet substrate 10. The pure matrix layer 20 is composed of a degradable or water-soluble second material and the toxin-containing matrix layer 30 is composed of a degradable or water-soluble third material and the Cry polyhedron. The toxin-containing matrix layer sustainably releases the Cry polyhedron to the water on which the insect control sheet is floated.
Abstract:
This invention provides a novel method for producing a lactide-lactone copolymer. The method is characterized by copolymerizing a lactide and a lactone using a molybdenum compound as a catalyst.
Abstract:
A method for refolding an antibody, a process for producing a refolded antibody, a refolded antibody, and uses thereof are provided. A method for refolding an antibody in a liquid phase comprises the steps of denaturing an inactive antibody binding directly or through a linker to a peptide, the peptide having an isoelectric point lower than the isoelectric point of the inactive antibody, and dispersing in a liquid phase the peptide-binding inactive antibody denatured in the step above. Also provided is a process for producing a refolded antibody.
Abstract:
There is provided a calorimeter. Heat flows in and out of the sample via a thermoelectric module. The thermoelectric module is so constituted that a pair of a P-type thermoelectric element and an N-type thermoelectric element is disposed between substrates, and the pair of the thermoelectric elements are connected in n pairs so that the P-type thermoelectric elements and the N-type thermoelectric element are arranged alternately in π-shape; a calorimetric sensitivity of the thermoelectric module of a thermal conductance surrounding thermoelectric module and a thermal conductance between substrates of the thermoelectric modules and a noise based on an electric resistance of the thermoelectric module depend on an L/A ratio of the thermoelectric element constituting the thermoelectric module and the number n of the pairs of the thermoelectric elements, where the L/A ratio is 6 mm−1 or more, and the number n of the pairs is 4 or more.
