Abstract:
PROBLEM TO BE SOLVED: To provide a method for expressing and purifying full-length class A penicillin-binding protein from bacteria, and a high-throughput screening method for antibiotic using the protein.SOLUTION: The method of purifying full-length class A penicillin-binding protein includes: amplifying DNA sequence of full-length penicillin-binding protein from bacterial genomic DNA; cloning the DNA sequence into a vector; expressing the DNA sequence in a host cell to obtain a full-length penicillin-binding protein; solubilizing the protein with a detergent; and purifying the protein.
Abstract:
PROBLEM TO BE SOLVED: To provide a wide-field super-resolution optical microscope using a spatial light modulator, and to provide a method for the same. SOLUTION: A light source 110 forms light beam having a spatial pattern, thereby successively illuminating a sample 160 at each phase of a plurality of phases. A detector 170 detects a first image of the sample in a first distance resolution and a first directional resolution, wherein individual phases in a plurality of phases illuminating each image are relative to one another. A processor 180 prepares a strong sectional image sample by processing the first image, prepares data showing a second image in the second distance resolution and thereafter forms the sectional image data of the sample 160 strengthened in a second directional resolution by performing spectrum analysis.

Abstract:
PROBLEM TO BE SOLVED: To provide a lumbrokinase dry powder containing a much active component, capable of controlling product quality and industrially mass-producible, and to provide a method for producing the same. SOLUTION: The lumbrokinase dry powder contains ≥60 wt.% protein and has 14,000-28,000 U/mg enzyme activation value. The lumbrokinase dry powder is produced by washing live earthworm with water, putting the washed earthworm in a sugar or sodium chloride, leaving to stand at room temperature, stimulating the earthworm to spew the secretion in the digestive tract, adding water to the earthworm body to cause cytoclasis, preparing a homogenate slurry thereof, removing crude residue from the obtained homogenate slurry, performing supernatation, collecting eluant by using an anion exchange chromatography column or an affinity chromatography column, concentrating, desalting and, degerming, and treating the degermed supernatant by lyophilization to obtain the powder.

Abstract:
PROBLEM TO BE SOLVED: To eliminate the trouble to manually distribute a visiting card each time information on the owner changes by generating a database of visiting card information. SOLUTION: The database of visiting card information is generated through a stage (201) for registering applicants for visiting cards, a stage (202) for receiving card information from applicants, a stage (203) for specifying a card identifier for the card information, and the stage (203) for specifying a password for the card information. The card information includes a classification defining the level of access to the card information. The card information is stored in the database while related to the card identifier, classification, and password.
