20130230897 | COMPLEX OF LABELED PROBES AND WATER-SOLUBLE CARRIER - The purpose is to produce, with high reproducibility, a complex of labeled probes and a carrier, said complex being to be used for detecting and measuring a target substance to be measured with high sensitivity and high stability. The means for accomplishing the purpose is that a label is bound to a probe-water soluble carrier conjugate using specific binding of an avidin compound such as avidin, streptavidin, etc. to biotin, and the binding of the avidin compound to the probe is performed before the binding to the carrier. Namely, after conjugating the avidin compound to a substance which is capable of binding to the target substance, the conjugate is bound to a high-molecule water-soluble carrier to produce a complex of the avidinized probes and the water-soluble carrier. Then the complex of the avidinized probes and the water-soluble carrier is mixed with a biotinylated label. Thus, a stable complex of the labeled probes and the water-soluble carrier, which enables the highly sensitive detection and measurement of the target substance, can be obtained with high reproducibility via the specific binding of the avidin compound to biotin. | 09-05-2013 |
20130189779 | HEPATITIS C VIRUS GENE - Disclosed are an HCV gene having higher replication efficiency and higher reinfection efficiency than the known HCV gene of genotype 1b, an RNA replicon having this gene, a cell infected with this RNA replicon, which cell allows replication of HCV, and an HCV particle. The hepatitis C virus gene encodes an amino acid sequence wherein the 979th amino acid is threonine; the 1804th amino acid is leucine; and the 1966th amino acid is lysine. An HCV gene which can propagate in vitro and has higher replication efficiency and higher reinfection efficiency than the known HCV gene of genotype 1b was provided. | 07-25-2013 |
20100291546 | METHOD FOR DETECTION OF HEPATITIS B VIRUS - To provide a method for detection or quantification of hepatitis B virus (HBV) antigens in serum and a simple and highly user-friendly method for sample treatment for use in the detection or quantification thereof. The method for treatment of a sample containing hepatitis B virus (HBV) is characterized in that release of HBV antigens and disruption of antibodies that bind to HBV antigens are carried out by treating a sample containing HBV with a treatment agent containing (1) an acidifying agent and (2) a protein denaturant or an amphoteric surfactant or cationic surfactant having an alkyl group and a tertiary amine or a quaternary ammonium salt within a molecule. | 11-18-2010 |
20100248274 | ANTIBODY DIRECTED AGAINST PRO-GASTRIN RELEASING PEPTIDE, AND USE THEREOF - Disclosed is a novel high-sensitive ProGRP measurement method, which is free from problems such as the fluctuations in measurement values and the operational constraints (e.g., the constraints on the handling of a sample). Specifically disclosed is a method for the measurement of a gastrin-releasing peptide precursor and/or a digested product thereof using at least two different antibodies each of which can recognize an epitope represented by the amino acid sequence consisting of amino acid 47 to amino acid 68 of the amino acid sequence set forth in SEQ ID NO:1. The method can detect a ProGRP or a digested product thereof in a refrigerated sample within a shorter period, by using the sample in a smaller amount, and with a higher degree of detective sensitivity, compared with the conventional methods. | 09-30-2010 |
20090017443 | Method for Detection of Hepatitus B Virus - To provide a method for detection or quantification of hepatitis B virus (HBV) antigens in serum and a simple and highly user-friendly method for sample treatment for use in the detection or quantification thereof. The method for treatment of a sample containing hepatitis B virus (HBV) is characterized in that release of HBV antigens and disruption of antibodies that bind to HBV antigens are carried out by treating a sample containing HBV with a treatment agent containing (1) an acidifying agent and (2) a protein denaturant or an amphoteric surfactant or cationic surfactant having an alkyl group and a tertiary amine or a quaternary ammonium salt within a molecule. | 01-15-2009 |
