摘要： PROBLEM TO BE SOLVED: To provide a means for efficiently producing a small comb frame having the half width from a conventional comb frame for apiculture. SOLUTION: This fitting tool for the bee comb frame is characterized in that an upper crosspiece receiver and a bottom crosspiece receiver are installed in the upper end of a vertical frame and at the lower end thereof respectively, and a suspending part is installed in the reverse side of an opening part of the upper crosspiece receiver. The small comb frame is obtained by attaching the upper crosspiece and bottom crosspiece which are divided into halves to the upper crosspiece receiver and the bottom crosspiece receiver of the outfitting for the bee comb frame respectively.

摘要： PROBLEM TO BE SOLVED: To easily replace filters placed surrounding around an exciting light source. SOLUTION: An ultraviolet lamp 16 is supported in between the top plate 14 of an almost box shape light source housing part 11 and the bottom plate 15. On the filter face 17a of a square tube shape filter 17 formed of nonwoven fabric carrying titanium oxide, a slit 17b is formed along the longitudinal direction. The filter 17 can be mounted on a prescribed position by only pushing the filter 17 into the side plate 13 even in a condition the ultraviolet lamp 16 is mounted on and removed from the light source housing part 11 by only drawing out.

摘要： PROBLEM TO BE SOLVED: To efficiently obtain a protein useful for medicines, etc., in a high yield by inoculating a virus in which a gene coding for the protein is integrated into a silkworm in a state of chrysalis. SOLUTION: A virus in which a gene coding for a protein is integrated is inoculated into a silkworm such as silkworm of exarate pupa system in a state of chrysalis and proliferated in a body of silkworm and the objective protein is collected from the chrysalis. Furthermore, the virus is preferably a silkworm nuclear polyhedrosis virus losing a part or all of cysteine protease gene which exists on a genome or replaced with a marker gene.

摘要： PURPOSE: To purify in large quantities at low cost luciferase involving bioluminescence, useful as e.g. a clinical test agent, by subjecting a luciferase-contg. liquid to affinity chromatography using ATP, NAD or an analogous compound thereof. CONSTITUTION: A luciferase-contg. solution prepared from the body fluid or ground product of silkworm infected with the virus recombined with luciferase gene is put through a hydrophobic column with phenyl group as ligand; the resultant adsorbate is then eluted, and the eluate is purified by an affinity chromatography with adenosine triphosphate(ATP), nicotinamidadenine dinucleotide(NAD) or an analogous compound thereof, thus economically obtaining in large quantities the objective purified luciferase involving bioluminescence such as for firefly and usable as e.g. a clinical test agent by DNA probe method.

摘要： PURPOSE:To obtain the subject high-purity protein useful as a vaccine having high safety and effectiveness by adsorbing an influenza HA protein-containing solution manifested by an insect cultured cell by using recombinant DNA technology on a specific saccharide molecule immobilized to a carrier and eluting. CONSTITUTION:A recombinant virus for manifesting an influenza HA protein integrated into a DNA encoding influenza HA protein is inoculated into an insect (e.g. silkworm larva) or an insect culture tissue to infect the insect, etc. On the fifth to the sixth day, the insect or the insect culture tissue is homogenized, centrifuged at high speed, precipitate is collected, dissolved in 10mM phosphoric acid buffer solution containing a surfactant, the solution is ultracentrifuged and a supernatant liquid is collected to give an influenza HA protein- containing solution. Then the solution is adsorbed on a compound comprising three or more saccharide molecules containing NeuAc alpha2, 3(6)Galbeta1, 3(4) as a free end immobilized to a carrier such as agarose gel, etc., and the adsorbed solution is eluted to give the objective purified influenza HA protein.

摘要： PURPOSE:To obtain a new substance capable of increasing the manifestation of useful substances through promotion of infecting insect cultured cells, etc., with recombinant virus, by heat treating silkworm body fluid followed by gel filtration thereof. CONSTITUTION:This virus infection factor is obtained by heat treating the body fluid taken from silkworm followed by gel filtration. This factor has the following characteristics: deactivating with trypsin or papain; adsorbable to cation exchange column; >=pH 9 in isoelectric point; and 10-50KDa in molecular weight. Specifically, this factor can be obtained by heat treatment of the body fluid taken from silkworm pref. at 60-70 deg.C for 30-60min followed by centrifugal separation of the fluid at 3000-5000rpm for 20-30min and then get filtration of the resultant supernatant using a gel such as Sephadex or Sepharose. It is recommended that the assay of this virus infection factor be conducted by a luminoassay technique using nuclear polyhedrosis virus recombined with the glowfly luciferase gene.

摘要： PURPOSE:To provide a gate apparatus attached to a nest box of a flower-visiting insect and having a nest-outlet path and a nest-inlet path separated from each other to allow the insect to transport a drug or pollen for the crossing of a self-incompatible plant and free from phytotoxicity caused by the drug and to provide a method for allowing an insect to transport a drug or pollen. CONSTITUTION:The inside of a gate apparatus 1 is separated into a nest-outlet path 3 and a nest-inlet path 4 with a partition plate 2 perpendicular to a platform 9. A side wall 10 is perpendicularly bent toward the platform 9 and an end outlet port 6 of the nest outlet path 3 is formed between the partition plate 2 and the side wall 10. The outlet port 6 is positioned inside of the inlet port 8 of the nest inlet path 4. The box is covered with a removable lid 12 and an escape-prevention net 13 is attached to the reverse side of the lid 12. A lighting hole 14 is formed at an end of the side wall 11 near the end outlet port 6 of the nest-outlet path 3 and a drug-application sheet 11 is pasted on the bottom face and the inner wall face of the nest-outlet path 3. A drug or pollen is applied to the drug-application sheet 11 to apply the drug or pollen to an insect leaving the box through the nest-outlet path and allow the insect to transport the drug, etc.
