摘要:
Fibrinolytic enzymes are produced and then isolated from non-cancerous established cell lines, designated as BEB or GPK. These fibrinolytic enzymes differ from those produced by malignant cell lines.
摘要:
A polypeptide derived from leeches of the species Hirudinaria manillensis has the following amino acid sequence: ##STR1## wherein Xaa indicates any amino acid residue; D indicates Cys or Pro; E indicates Glu, Asp or His; F indicates Asp, Lys or Trp; or a pharmaceutically acceptable salt, derivative or bioprecursor thereof. The polypeptide, and fragments thereof, is a specific anti-thrombin useful as a medicament.
摘要:
A method for preventing the formation of platelet-rich clots or thrombus, and for deaggregating platelet-rich clots or thrombus, using hementin, a polypeptide derived from leech salivary glands. Hementin may be administered for this purpose in a pharmaceutically acceptable carrier or excipient, with or without additional anticoagulants such as hirudin, hirudin analogues, or an inhibitor of factor Xa.
摘要:
This invention relates to a novel protease-inhibitor,--which we called GELIN--and to pharmaceutical and cosmetic preparations thereof, containing this compound. GELIN is an inhibitor of human and porcine leucocyte elastase and chymotrypsin. GELIN has specific antibiotic properties. It also relates to the novel use of EGLIN, another chymotrypsin-inhibitor in cosmetic preparations.
摘要:
A method is provided for treating a viral infection in a subject by administering a surfactant and/or a steroid so as to produce a high concentration thereof in the systemic circulation. The method is particularly applicable to the treatment of HIV infections. The use of surfactants and/or steroids in the production of pharmaceutical compositions is described.
摘要:
A method of providing an electrical circuit wherein a carrier, which is a film of insulating plastic material with a circuit pattern thereon is supported in a mould and a moulding material is applied by the application of heat and pressure to provide a substrate so that the circuit is embedded in or within a three-dimensional surface of the moulded substrate.
摘要:
Affinity chromatography media are prepared by reacting mono or di-chloro triazine dyes with a solid support matrix containing free hydroxy or amino groups in the presence of an alkali metal hydroxide and an alkali metal salt. In the absence of cyanogen bromide activation, the linkage to the support is entirely via the triazine ring giving high and specific protein-binding capacity. Suitable support matrices include polymers and copolymers of agarose, dextrose, dextran and acrylamide with agarose being particularly preferred. Dye binding levels are much higher than those obtained in the presence of carbonates or bicarbonates.Mono-chlorotriazinyl dyes are bound at a pH which is preferably above 9.5. The reaction time is about 40-60 hours at room temperature, however this may be reduced if the reaction temperature is increased. Dichlorotriazinyl dyes are bound at pH 8 to 12.5 in a few hours at room temperature.The media may be used for the efficient and often highly specific purification of a wide variety of proteins, including enzymes and blood proteins.
摘要:
Modified microorganisms are prepared by inactivation of the endogenous lactate dehydrogenase gene. The microorganisms are deposited under NCIMB Accession Nos. 41277, 41278, 41279, 41280 or 41281.
摘要:
The present invention is a method for the production of thermophilic microorganisms suitable for the production of ethanol, comprising: (i) culturing a thermophilic microorganism under aerobic or anaerobic conditions in a suitable culture media; and (ii) incorporating amounts of ethanol into the culture media to induce ethanol tolerance.
摘要:
A thermophilic micro-organism comprising a modification that increases amylase expression and starch hydrolysis compared to wild-type, wherein the modification is insertion of a heterologous amylase gene.
