Thrombin-binding substances are obtained by fractionating human urine by ion-exchange chromatography, affinity chromatography using a thrombin-bound carrier, immune adsorption column chromatography, gel filtration, and/or molecular-weight fractionation. One of the substances has a molecular weight of 46,500.+-.6,000 in reduced condition and 39,000.+-.10,000 in unreduced condition by SDS PAGE and an isoelectric point at pH 5.0-5.3, while the other has a molecular weight of 40,000.+-.8,000 in reduced condition and 31,000.+-.10,000 in unreduced condition by SDS PAGE and an isoelectric point at pH 4.9-5.7. They have strong affinity to thrombin. They are capable of promoting the thrombin catalyzed activation of protein C and prolong clotting time. They are stable to denaturing agents (urea and sodium dodecylsulfate).
摘要:
An improved multifilament superconductor is fabricated by the method in which a tin rod or tin based alloy rod is clad with a copper based alloy tube, the thus obtained copper-clad rod is further clad with a niobium based alloy tube, and a copper material is applied as a stabilizer on an outer peripheral surface of the niobium based alloy tube to form a composite. This composite is then reduced and thermally treated at a temperature ranging from 640.degree. to 770.degree. C. to thereby form an Nb.sub.3 Sn superconductor composite with a filament tube therein. At least one of the copper based alloy tube and the niobium based alloy tube contains 0.1-5.0 at. % titanium, and in addition, the tin based alloy rod may contain 0.1-3.5 at. % titanium. The tin is contained in the copper-clad rod at weight % of about 25-85, preferably 30-80 weight %.

The present invention provides a production method for biofuel based on a technology to convert carbon-dioxide as a carbon source through photosynthesis by photosynthetic microorganisms to biomass and produce biofuel of the biomass. The production method for biofuel of the present invention comprises a culturing process (S1) of culturing in a culture solution photosynthetic microorganisms which store oils, fats and carbohydrates in cells of the photosynthetic microorganisms, an oil and fat conversion process (S2) of converting the carbohydrates stored in the cells of the photosynthetic microorganisms cultured in the culture apparatus to oils and fats, an extraction process (S3) of extracting the oils and fats out of the cells of the photosynthetic microorganisms, and a reforming process (S4) to reform the extracted oils and fats.
