摘要:
According to the present invention, α1,4-GalNAc transferase can be produced in a large amount by using a microorganism. Also, a GalNAc-containing complex carbohydrate can be economically produced in a large amount by contacting a microorganism expressing the transferase, UDP-GalNAc and an acceptor complex carbohydrate in an aqueous medium.
摘要:
The present invention provides branched polyalkylene glycols useful as a chemically modifying agent for physiologically active polypeptides, wherein two single-chain polyalkylene glycols are linked to a group having a cyclic structure other than a plane structure, and wherein a group having reactivity with an amino acid side chain, an N-terminal amino group or a C-terminal carboxyl group in a polypeptide or a group convertible into the group having reactivity is linked to the group having a structure other than a plane structure.
摘要:
A monoclonal antibody that recognizes each of the epitopes present at the 10th to 220th, 221st to 297th and 469th to 662nd positions from the N-terminal amino acid of human Mx protein MxA and reacts specifically with the Mx protein by western blotting, immunoprecipitation or immunocyte staining; and a hydbridoma that produces the antibody. This antibody is useful for diagnosing viral infection.
摘要:
The present invention provides a transgenic non-human mammal which has DNA encoding a foreign reporter protein for monitoring changes in intracellular calcium ion concentration and expresses the reporter protein in one or more types of non-neuronal cells; a method for producing the above transgenic non-human mammal; a method for detecting changes in intracellular calcium ion concentration using the above transgenic non-human mammal; DNA having promoter activity which is used for production of the transgenic non-human mammal; and the method of use of the DNA. The non-human mammal of the present invention expresses the DNA in one or more tissues or organs selected from the group consisting of epithelial tissue, connective tissue, adipose tissue, cartilage tissue, bone tissue, muscle tissue, intraoral tissue, blood tissue, bone marrow, cardiovascular organ, lymphatic organ, teeth, digestive tractl, liver, gallbladder, pancreas, respiratory organ, urinary organ, genital organ, endocrine organ, sense organ and nail, and can be used for evaluation of pharmacological effect and activity of physiologically active substances (for example, drug), novel gene products having unknown functions and the like in these tissues or organs.
摘要:
Methods and means are described for diagnosing a disease or a predisposition to disease by genotyping a klotho gene from an individual and identifying the presence of one or more risk polymorphisms. These risk polymorphisms are associated either directly or indirectly with predisposition to a range of chronic diseases including osteoporosis, skin disorders, age-related disease, lung dysfunction and metabolic syndrome. Methods of treatment, kits for diagnostic purposes and an isolated klotho gene including all or some of a range of polymorphisms are also described as well as methods of isolating molecules that modulate a klotho gene.
