摘要:
Column packings for liquid chromatography comprising porous granules which have hydrophilic surfaces prepared by calcining a crystalline clay mineral having a fibrous structure. Median pore diameter of the porous ceramic granules is in the range of from 0.001 .mu.m to 0.01 .mu.m. The crystalline clay mineral can be sepiolite or attapulgite. The column packings for liquid chromatography have high mechanical strength, are presssure resistant and very stable to elutants having a high pH value and/or a high polarity so that the separating characteristics thereof are not changed even after long use.
摘要:
An edible oil or fat improved in oxidative stability and suppressed in the development of off flavor is obtained without impairment of high physiological functions inherent to highly-unsaturated fatty acids. To obtain the edible oil or fat, a specific polyunsaturated fatty acid-base oil or a particular fat and saturated fatty acid-base oil or fat are mixed and subjected to an interesterification reaction so that fatty acids are caused to bond at random on glycerol skeletons of the oil or fat to achieve the following properties: (a) the content of polyunsaturated fatty acids of at least three unsaturated bonds per molecule in fatty acid residual groups: 5 to 30%, (b) the content of saturated fatty acids free of any unsaturated bond: 50 to 80%, (c) iodine value: at least 35, and (d) melting point: 35.degree. C. or higher.
摘要:
This invention relates to a monoclonal antibody having affinity to human TCF-II without any affinity to HGF and determination or purification methods of TCF-II using the antibody. The monoclonal antibody can be obtained by adding a blocking solution containing a surface active agent to the culture medium containing monoclonal antibody to block antibodies other than said monoclonal antibody, followed by reaction with a solid phase antigen, TCF-II. Human TCF-II can be selectively and effectively purified or determined without any influence of the presence of HGF by using the antibody.
摘要:
The invention relates to an osteoblast growth and bone enhancing factor or factors having a molecular weight of about 5,000 to 28,000 daltons and an isoelectric point of 4 to 9, which is isolated from whey or whey protein. The invention includes various methods for obtaining the factor or factors from whey and whey protein. The factor or factors from whey and whey protein may be incorporated in foods, medicines and feeds for preventing or treating osteoporosis and other maladies in joints of bones.
摘要:
The new glycoprotein, which possesses an anti-tumor activity, a leukemia cell differentiation inducing activity, a cellular immunology enhancing activity, a vascular endothelial cell growth stimulating activity and a hepatocyte growth stimulating activity, can be obtained.
摘要:
A method of producing cheese-type food from powdered milk as a starting material, prepared by ultrafiltrating milk, adjusting the ultrafiltrated milk to pH 5.0-5.8 and by spray-drying it, which is then heated and melted with an addition of emulsifying salts. Also a method or producing aged-type cheese by ripening green cheese processed from powdered milk, prepared by adding lactic-acid bacteria starter to ultrafiltrated milk and dried.
摘要:
This invention provides pharmaceutical preparations containing highly concentrated tumor cytotoxic factor (TCF). The pharmaceutical preparations of the present invention contain highly concentrated TCF and a basic amino acid or their salts, or an organic or inorganic salt as a solubizer. The resultant compositions described in the present invention dissolve TCF at high concentrations of 10 mg/ml or over under about neutral and isotonic conditions. The resultant compositions are stable and are suitable for injection preparations.
摘要:
A physiologically active compound HS-1 having the following chemical structure is disclosed. This compound is prepared by culturing Chromobacterium violaceum, adding tryptophan and diethyldithiocarbamate (diethyldithiocarbamic acid) to the culture broth for reacting with the cells for producing HS-1 in the cells, and collecting the compound from the culture broth. This novel compound possesses antitumor and antimicrobial activity, and is effective as an antitumor agent or an antimicrobial agent. ##STR1##
摘要:
Efficient utilization of a whey protein for the production of cheese, which results from the cheese production as a by-product. The whey is concentrated by an ultrafiltration and added to the concentrated milk. A milk coagulating enzyme and a lactic acid bacteria starter were added to the resultant mixture together with warm or hot water with stirring to instantaneously elevate the temperature of the reaction mixture to coagulate and give the cheese curd.
摘要:
Sialic acid binding proteins, sialic acid-binding peptides and sialic acid containing oligo-saccharides are active ingredients of a novel bacterial enterotoxin neutralizer and interfere with the binding of enterotoxins, including cholera toxin, to receptors so as to exert an effect of neutralizing the toxicity, thus being utilized as an effective neutralizer and are safe and available cheaply and abundantly from by-products produced during the processing of cow's milk which renders the enterotoxin neutralizer economically advantageous for commercial use.
