41 results about "Hepatitis C virus Antibody" patented technology

The invention discloses a kit for detecting a hepatitis c virus antibody as well as a detection method and an application thereof, and belongs to the technical field of in vitro diagnosis and detection. The kit consists of the following components: (1) a magnetic microsphere system: including a magnetic microsphere and an HCV antigen in indirect connection by virtue of a first bridged compound; and (2) a marker system: including an HCV fusion antigen and a marking tracer which are in indirect connection by virtue of a second bridged compound, wherein the HCV antigen and the HCV fusion antigen are combined with an HCV antibody on different sites. The kit and the detection method, by detecting the hepatitis c virus antibody through chemiluminescence immunoassay, have the advantages of high sensitivity, good specificity and broad detection scope.

This invention relates to humanized antibodies and fragments thereof which bind to hepatitis C virus E2 protein and methods of their use.

The invention relates to a diagnostic reagent kit for testing the hepatitis c virus (HCV) and the preparation and test method, which is to add the HCV recombinant antigen used for peridium into the buffer solution, blend it, move into the luminous microplate, make incubation for 18 hours under 4DEG.C, wash the luminous microplate, add into the confining liquid, leave the liquid after incubation and fully dry the luminous microplate to complete the preparation of the pre-peridium luminous microplate; combine the anti-human IgG used for marking and the horse radish peroxidase by improving the sodium periodate to complete the preparation of the enzyme marker; prepare the chemical luminous substrate solution A with luminal, Tween20 and luminous intensifier and prepare the chemical luminous substrate solution B with the hydrogen peroxide. The reagent kit also comprises the sample diluent and concentrated scrub solution. The negative corresponds to the normal human serum while the positive corresponds to the people with serum of pooled serum with HCV antibody. The reagent kit provided in the invention has much higher detection sensitivity than the ELISA, which is safe and reliable, easyto operate with low cost, and without any expensive full-automatic chemical luminous measuring apparatus required.

This product is a test strip for the rapid detection of hepatitis C virus antibody saliva. The test strip is composed of a bottom plate and a casing. Colloidal gold-labeled Protein G, nitrocellulose membrane coated with recombinant antigen specifically binding to hepatitis C virus antibody (test line), and a goat anti-human IgG (quality control line). The rapid detection test strip has the advantages of good conservation and strong specificity, can detect infection by hepatitis C virus of all genotypes (types 1-6), and is not interfered by hepatitis B virus and the like.
