摘要:
A DNA polymerase from Thermus thermophilus which retains at least 60% of its activity when placed at pH 8.0 and 85.degree. C. for 2 hours is disclosed. The DNA polymerase has a pH optimum of about 8.0, a temperature optimum of about 75.degree. C., a mass of about 85 to 95 kDa and an optimal saline concentration of about 20-60 mM NaCl.
摘要:
Cotton plants of the genus Gossypium with improved cotton fiber characteristics are disclosed. The cotton plant has an expression cassette containing a gene coding for an enzyme selected from the group consisting of endoxyloglucan transferase, catalase and peroxidase so that the gene is expressed in cotton fiber cells to improve the cotton fiber characteristics. Also disclosed is a method for producing cotton fibers with improved fiber characteristics from these cotton plants.
摘要:
A recombinant vector comprising an incorporated chromosome DNA fragment containing a PvuI restriction enconuclease gene derived from Proteus vulgaris, a host transformed with the recombinant vector and a method of producing PvuI restriction endonuclease characterized in that the transformed host is cultivated and PvuI restriction endonuclease is harvested from the resulting culture. Since the host transformed with the recombinant vector of the present invention produces PvuI alone, it is unnecessary to remove PvuII in the purification process for PvuI, and further, since its productivity for nonspecific DNase is lower in comparison with conventional producer bacteria, DNase can be removed easily, making the production of PvuI easy.
摘要:
When a method of operating a player character 40 is displayed on a first LCD 11, a movement of an enemy character 41 displayed on a second LCD 12 temporarily stops and the player character 40 moves from a display screen of the second LCD 12 to a display screen of the first LCD 11. Thus, a player's sight line is guided from the display screen of the second LCD 12 to the display screen of the first LCD 11 along with the movement of the player character 40, thereby allowing the player to confirm; with no oversight, that explanatory information regarding the method of operating the player character 40 is displayed.

摘要:
A method for producing glycoconjugate, which comprises the steps of:(i) binding a sugar residue to the side chain of a water-soluble polymer via a linker having a selectively cleavable linkage to give a primer, and bringing said primer into contact with an immobilized glycosyltransferase in the presence of a sugar nucleotide, to transfer a sugar residue of said sugar nucleotide to the sugar residue of said primer,(ii) elongating a sugar chain by transfer of plural sugar residues by repeating the step (i) at least once,(iii) removing, where necessary, a by-produced nucleotide or an unreacted sugar nucleotide, and(iv) repeating the steps (i)-(iii) where necessary and releasing the glycoconjugate by selectively cleaving the cleavable linkage in the linker, from the above-mentioned primer connecting the sugar chain elongated by the transfer of plural sugar residues,and a method for producing a sphingoglycolipid.
摘要:
Methods are disclosed to achieve an improvement in the characteristics and yield of cotton fibers. In one method, a cotton plant of the genus Gossypium in seed form or in growth stage is treated with a brassinosteroid. In another method, an ovule culture is prepared from a cotton plant of the genus Gossypium in a brassinosteroid-containing liquid medium. Cotton fibers with improved fiber characteristics are obtained from the cotton bolls of the treated plant or from the cultured ovules. Also disclosed are a method for inducing specific genes expression in a cotton plant to produce cotton fibers with improved fiber characteristics by treatment with a brassinosteroid, and a cotton plant produced by this method; as well as a novel gene capable of changing the degree of its expression found in the ovules of a cotton plant treated with a brassinosteroid, a gene capable of hybridizing with this novel gene, a recombinant plasmid containing this novel gene, a transformant containing this recombinant plasmid, and the like.
