摘要:
A reagent for determination of human blood coagulation factor XIII for reversed passive hemagglutination reaction which comprises sensitized erythrocytes prepared by sensitizing animal erythrocytes with specific anti-human factor XIII antibody, and a kit using the reagent are disclosed.
摘要:
An antithrombin preparation, secure and stable for a long period of time, can be obtained by freeze-drying an aqueous solution containing antithrombin-III as main component in the presence of an effective quantity of at least one member selected from the group consisting of proteins, sugars, amino acids, inorganic salts and salts of organic acids as stabilizer.
摘要:
Physiologically active substances such as antibiotics can preferentially be carried to a morbid part, for example, injured tissue and neoplastic cell proliferation site by administering its complex with fibronectin to repair the morbid part. The complex is prepared by the reaction between the physiologically active substance and the fibronectin with or without intervention of a protein cross-linking agent.
摘要:
Benzodiazepine derivative represented by the following general formula or pharmaceutically acceptable salt thereof: ##STR1## wherein R.sup.1 is --COR.sup.4 (R.sup.4 is a carboxylic acid residue) or an alkyl or aralkyl group (these groups have a substituent selected from a carboxyl group, an amino group and a cyano group), R.sup.2 is a lower alkyl group and R.sup.3 is a hydrogen atom or a lower alkyl group.The above compound is low in toxicity and has an antitumor activity.
摘要:
A process for recovering interferon which comprises contacting a solution containing an interferon produced by the induced cells of human origin with a water-insolubilized sulfated polysaccharide to allow the interferon to be adsorbed on the water-insolubilized sulfated polysaccharide and then selectively eluting the interferon with an aqueous solution of an inorganic salt.
摘要:
Interferon can be recovered simply by contacting an aqueous solution containing interferon which is induced and produced from cells of human origin capable of producing interferon, with a siliceous substance to adsorb interferon on it and eluting the adsorbed interferon with an aqueous solution containing a nonionic surfactant, preferably further containing an acriflavine such as acrinol.
摘要:
Complexes of albumin combined with organic dibasic acid half esters, such as those of succinic acid and phthalic acid, of 7-hydroxycholesterol are soluble in water and have excellent immunosuppressive and anti-inflammatory action.

摘要:
A process for heat treatment to inactive hepatitis virus in human blood coagulation factor XIII compositions, which is characterized in that the heat treatment at 50.degree. to 80.degree. C. of an aqueous solution containing the human blood coagulation factor XIII is carried out for 3 to 15 hours in the presence of 10% (W/V) or more of at least one principal stabilizer selected from the group consisting of neutral amino acids, monosaccharides and sugar alcohols and 10% (W/V) or more of at least one auxiliary stabilizer selected from the group consisting of salts of organic carboxylic acids having 3 to 10 carbon atoms.
摘要:
Human urine-origin colony-stimulating factor and kallikrein are separated in pure form, respectively, from an aqueous solution thereof, such as a urinary protein-concentrated solution by subjecting the solution added with a stabilizer such as octyl-phenoxypolyethoxyethanaol or polyethylene glycol both having a molecular weight of 1,000-10,000, to high-performance gel filtration effective in molecular exclusive limit of 10.sup.5 -5.times.10.sup.5 as determined with globular protein.
