Abstract:
An antibody specific to intracellular domains of at least two protein tyrosine phosphatases; a process for preparing the same; and cells producing the above antibody. This antibody, which has specificities to intracellular domains of both of phosphatase subunits LAR and CD45, is useful in analyzing and quantitating PTPs, identifying and detecting a novel PTP, acquiring a novel phosphatase by cloning, etc., as well as developing a diagnostic method useful in insulin resistance and NIDDM, preventing, treating (curing, etc.) and diagnosing various symptoms of syndrome X based on insulin resistance, and preventing and diagnosing the onset of arteriosclerosis and heart diseases.
Abstract:
The present invention provides a composition for safely and effectively preventing and treating digestive organs diseases, particularly, gastric ulcer, duodenal ulcer, gastritis, diarrhea, enteritis and the like. There is also provided a composition having a novel mechanism of action in order to solve the problems which was difficult to be solved by the side effect previously known mechanisms of action. More particularly, there is provided a pharmaceutical composition containing an ingredient which activates PAR-2 as an essential ingredient, which is useful for inhibiting gastric acid secretion, promoting digestive tract mucus secretion, protecting digestive tract mucosa, repairing tissue of digestive organs, and preventing and treating digestive organs diseases.
Abstract:
A nucleic acid sequence for potentiating the expression of a useful gene which contains a sequence carried by the 5'-nontranslational region, its fragment or its variant and is capable of potentiating the expression of a gene to thereby elevate the yield of the gene product; a vector containing the above nucleic acid sequence; host cells transformed or transfected by the above vector; a process for producing a useful gene product by using the vector; and a method for potentiating the expression of a useful gene by using the vector. Moreover, the above-mentioned sequence is useful in screening an initiation factor of interaction with IRES or IRES-dependency, treating diseases caused by the cap-dependent mRNA translation or a decrease in the IRES activity, or in diagnosing the severity of hepatitis C.
Abstract:
A method for quickly assaying the cAMP content or the adenylate cyclase activity in a biological sample containing endogenous non-cyclic adenine nucleotides without resort to any radioactive reagents. More particularly, a method for assaying the cAMP content or the adenylate cyclase activity in a biological sample containing endogenous non-cyclic adenine nucleotides selected from the group consisting of cAMP formed by endogenous adenylate cyclase, ATP, AMP, ADP and mixtures thereof which comprises: (1) adding efficacious amounts of apyrase, adenosine deaminase and alkaline phosphatase to the above sample to thereby enzymatically remove the endogenous non-cyclic adenine nucleotides other than cAMP and glycose-6-phosphate therefrom; (2) enzymatically converting cAMP into AMP; and (3) thus quantitating AMP without resort to any radioactive substances; and a kit for performing this method.
Abstract:
A recombinant conglutinin containing a collagen region comprising six amino acid residues containing two amino acid sequences Gly-Xaa-Xaa (SEQ ID NO:3, Xaa representing a protein-constituting amino acid residue), a neck region of natural conglutinin and a sugar-chain recognition region of natural conglutinin, having an antiviral activity (neutralizing activity), and being expected to be applicable for medicinal uses.
Abstract:
A method of detecting a nucleic acid which comprises bringing a solid carrier suspected to carry or contain a nucleic acid into contact with a polyamine containing, bound thereto, a label capable of generating a detectable signal or a precursor thereof to thereby form a complex between a nucleic acid, if any, and the polyamine, removing the polyamine which has not formed any complex before or after the conversion of the precursor, if used, into the label, and detecting the label.
Abstract:
A novel highly stable sodium diacetate crystal, in which the volatilization of acetic acid can be suppressed for a long period. More specifically, a sodium diacetate crystal having a median diameter in the range of 300 to 3000 µm.
Abstract:
