Abstract:
The present invention relates to a method of removing an intron contained in a gene from a eukaryotic gene, and linking only the exon sequences to prepare an expression vector comprising the linked sequences. Specifically, the invention relates to a method of preparing an expression vector containing linked exon sequences comprising amplifying exon sequences by PCR as one or more fragments from a giant fungal gene containing an intron, and linking the fragments together with a restriction enzyme-treated vector using the gap repair cloning method; a method of preparing an expression vector containing a full-length cDNA sequence by synthesizing and linking cDNA fragments from a fungal giant gene; a transformant having introduced therein an expression vector prepared by the method; a protein produced by the transformant; and a method of preparing a compound produced by the protein using the expression vector.

PROBLEM TO BE SOLVED: To obtain a paper string excellent in water and weather resistances and biodegradability and suitable for cultivating a plant without requiring removing and recovering operations and to provide a netlike supporting tool for cultivating the plant producible by knitting in or heat-seal joining using the paper string and excellent in the water and weather resistances and biodegradability without requiring the removing and recovering operations. SOLUTION: This paper string having water resistance is obtained by twisting a blend paper of biodegradable thermoplastic synthetic staple fibers comprising 20-90 wt.% of the biodegradable thermoplastic synthetic staple fibers and 10-80 wt.% of vegetable fibers for papermaking and having 15-80 g/m2 basis weight or a combination paper prepared by joining a layer containing the biodegradable thermoplastic synthetic staple fibers to at least one surface of a layer without containing the biodegradable thermoplastic synthetic staple fibers according to the combination and having 15-80 g/m2 basis weight. Furthermore, the netlike supporting tool for cultivating a plant is obtained by weaving the paper string or crossing the paper string without weaving and thermally fusing the interlaced parts or knitting the paper string therein.
Abstract:
PROBLEM TO BE SOLVED: To use biodegradable bag paper as a material for an industrial bag capable of being made by heat sealing and being degradated with microorganism, by a method wherein a layer capable of being heat sealed which contains a specific wt.% of biodegradable thermoplastic synthetic short fiber, and a layer incapable of being heat sealed which consists of natural fiber for making paper are bonded to each other by making paper together. SOLUTION: Biodegradable bag paper is manufactured by making paper together from a layer containing biodegradable thermoplastic synthetic short fiber and a layer consisting of natural fiber for making paper. The short fiber consists of a polycondensate of fatty glycol and fatty dicarboxylic acid, or biodegradable thermoplastic resin synthetic resin of polylactate series copolymer such as lactic acid and glycollide copolymer. A heat seal layer 2 capable of being heat sealed in which 30 to 90 wt.% of the short fiber is blended, and a non-heat seal layer 1 incapable of being heat sealed which consists of natural fiber for making paper are formed as paper made from two layers capable of being degradated with microorganism or as paper made from three layers wherein the non-heat seal layer 1 is made its intermediate layer by a paper-making method in a paper-making technique.
Abstract:
An anastomosis device 3 includes a corrugated circumference section (20;120;120'), a top-side slender member (10A-1;110A-1), and a bottom-side slender member (10B-1;110B-12). The top-side slender member (10A-1;110A-1) is connected to one top section (20A-1;30A-1;120A-1) of the corrugated circumference section (20; 120;120'). The bottom-side slender member (10B-1;110B-12) is connected to one (20B-1;30B-1;120B-12) at the corrugated circumference section (20;120;120').
Abstract:
An object of the present invention is to provide a method for distinguishing between prostate carcinoma and benign prostatic hyperplasia with high sensitivity and good reproducibility using a small amount of an analyte sample. The method for distinguishing between prostate carcinoma and benign prostatic hyperplasia according to the present invention as a solution means thereof comprises: bringing an analyte sample containing a prostate-specific antigen (PSA) into contact with a carrier having an anti-free PSA antibody immobilized thereon, thereby binding free PSA to the anti-free PSA antibody immobilized on the carrier; thereafter bringing the carrier in which the free PSA is bound to the immobilized anti-free PSA antibody into contact with a monoclonal antibody capable of specifically recognizing a glycan in which a terminal sialic acid residue is bound to galactose through an α(2,3) bond, thereby binding the monoclonal antibody capable of specifically recognizing a glycan in which a terminal sialic acid residue is bound to galactose through an α(2, 3) bond to the free PSA bound to the anti-free PSA antibody immobilized on the carrier; measuring the amount of the free PSA having an N-type glycan in which a terminal sialic acid residue is bound to galactose through an α(2, 3) bond; comparing the measured amount thus obtained with a preset cutoff value for prostate carcinoma and benign prostatic hyperplasia, thereby determining that when the measured amount is larger than the cutoff value, prostate carcinoma is developed or the probability of developing prostate carcinoma is high, and when the measured amount is smaller than the cutoff value, benign prostatic hyperplasia is developed or the probability of developing benign prostatic hyperplasia is high.
Abstract:
A method of providing a plant with stress resistance, comprising applying at least one substance (A) to the plant, said at least one substance (A) being selected from the group consisting of a compound represented by Formula (I) and the like and salts thereof. Phytotoxicity of a plant due to agricultural chemicals is reduced by providing the plant with stress resistance. [In Formula (I), R 1 to R 4 each independently represents a hydrogen atom, -SO 3 H, -PO 3 H 2 , a glycosyl group or -COR 11 . R 11 represents an unsubstituted or substituted C1 to C30 alkyl group or an unsubstituted or substituted C2 to C30 alkenyl group.].
Abstract:
Disclosed are: a method for identifying/analyzing a gene for an antibody in one cell derived from a human; a technique for producing an antibody derived from an identified one B cell; and others. A gene for an antibody specific to a melanoma antigen is analyzed/identified at a one-cell level by using an immortalized B cell produced from peripheral blood monocytes from a melanoma patient or a primary B cell included in the peripheral blood monocytes. It is found that B cells capable of producing a specific antibody can be separated on one cell by one cell basis by staining the B cells with a GST-labeled melanoma-specific cancer antigen MAGE1, an Alexa-labeled anti-GST antibody and a PE-labeled anti-human IgG antibody and carrying out the single cell sorting of the stained B cells. Further, a practical technique for extracting total RNA from the separated one B cell and cloning a gene for a specific antibody into the total RNA efficiently can be established.
