摘要:
The present invention is aimed at providing an anticancer agent which can inhibit the metastasis of cancer cells when used alone. In addition, the present invention is also aimed at providing an anticancer agent which can inhibit the metastasis of cancer cells while causing a small side effect and very small toxicity even for an extended time of administration. The cancer metastasis-inhibiting anticancer agent according to the present invention is characterized by containing sialic acid, its salt, a polymer of sialic acid or a salt of the polymer as an effective ingredient.

Therapeutic drugs for endotoxin blood symptom and multi-organ failure induced by it is provided, which therapeutic during are composed of sialic acid its salt, polymers of sialic acid or a salt of the polymer as effective components and have high therapeutic effects for shock death and organ failure induced by endotoxin as well as high safety, and are effective for treatment of endotoxin-shock, and organ failure.
摘要:
An enzyme-fixed bioreactor, including a reaction column, enzyme-fixed catalyst particles uniformly and densely filled in the reaction column, the catalyst particles being composed of carrier sepiolite particles consisting essentially of sepiolite and an enzyme carried on the surface of the carrier sepiolite particles. The bioreactor has stable heat resistant and chemical properties, high productivity, and is economically superior to prior art, without fear of destruction of the catalyst, short path, and clogging in the reaction column.

The hybridization device of the invention aims to attain a hybridization reaction of high reproducibility. A hybridization device 2 for a hybridization reaction of nucleic acid has a cover member 10 that defines a cavity 12, which includes a nucleic acid fixation area 6 of a substrate 4 for fixation of a nucleic acid probe and has capacity for storage of a liquid for the hybridization reaction therein. At least part of an area exposed to inside of the cavity 12 forms a hydrophobic region 18. Adequate control of the surface characteristic of the area exposed to the cavity for implementing the hybridization reaction desirably enhances the signal intensity and reduces a variation in signal intensity, thus attaining the hybridization reaction of high reproducibility.
摘要:
The present invention relates to the technology for inhibiting the cancer metastasis, and is aimed at the provision of a pharmaceutical composition for effectively inhibiting the metastasis of the cancer. A cancer metastasis inhibitor according to the present invention is characterized by containing a sugar chain separated from a surface of a Streptococcus agalactiae Ia type or Ib type as a main ingredient. Since the surface sugar chains of the Streptococcus agalactiae Ia type or Ib type have structures similar to surface sugar chains of the cancer cells, the former surface sugar chains adhere to E-selectin appearing in an intravascular endothelial cell, competitively inhibit the adhesion between intravascular endothelial cells and the cancer cells, and effectively prevent of the metastasis of the cancer, when the sugar chains exist in blood of a patient.
摘要:
Disclosed is a peptide immobilization technique which can achieve the immobilization of a satisfactory quantity of a peptide on a solid support. In the immobilization of a peptide on a solid support, a surfactant is allowed to coexist on the solid support together with the peptide. In this manner, the quantity of the peptide immobilized on the solid support can be increased.
摘要:
A DNA array for detecting a single nucleotide polymorphism of a gene, which comprises, on a solid support, a first probe spots group consisting of one or more probe spots each containing one or more probes hybridizable with a polynucleotide of the gene, in which the probes are exactly complementary to the first polymorphism pattern of the gene, and a second probe spots group consisting of one or more probe spots each containing one or more probes hybridizable with the polynucleotide of the gene, in which the probes are exactly complementary to the second polymorphism pattern of the gene, wherein probe lengths in the probe spots is different from each other. This DNA array enables more exact SNP detection.

Proliferation activity of methane bacteria in organic waste water can be improved by maintaining the ratio of the amounts of nickel, iron and cobalt contained in the waste water to the BOD thereof to not lower than certain values, and various organic waste waters, such as waste liquor formed during the production of beer and the like, can be treated in a high BOD removal ratio of not lower than 90% while maintaining a high BOD load of not lower than 10 kg/m.sup.3 .multidot.day.
摘要:
A device for preventing an outflow of a fuel vapor from a fuel tank comprising a breather pipe which connects the upper interior of the fuel tank to a charcoal canister. A float-valve assembly is mounted on the upper wall of the fuel tank. This assembly comprises a breather passage connected to the charcoal canister via the breather pipe, a normally closed solenoid valve arranged in the breather passage, and a float normally allowing the breather passage to be open to the interior of the fuel tank. When the replenishment of the fuel tank is carried out, the solenoid valve is opened to feed fuel vapor in the fuel tank into the charcoal canister.
