  • Patent number: 8110374
    Abstract: The invention relates to a method and an immunological test kit for predicting the risk of transplant rejection by detecting anti-AT1 receptor auto-antibodies in biological materials of a patient to be examined, e.g. by an immune reaction with the AT1 receptor or functionally analogous peptides or proteins thereof. The invention is also directed to the use of the AT1 receptor or functionally analogous peptides or proteins in order to predict (diagnose) the risk of transplant rejection. Said risk exists if anti-AT1 receptor auto-antibodies can be detected in such biological materials, e.g. in body fluids or tissues.

    Abstract: Provided is a mAb-based method for the detection of T cell stimulatory epitopes known to be involved in CD. The method has many advantages compared to the existing methods for the detection of gluten since it is the first method that can; (i) detect T cell stimulatory epitopes of gluten; (ii) detect the epitopes separately, (iii) detect T cell stimulatory epitopes present on gliadin and glutenin homologues present in other cereals also known to be involved in CD; and (iv) detect T cell stimulatory epitopes on both intact proteins and small protein fragments. The new method is a valuable tool in the screening of basic ingredients, semi manufactured ingredients and food products that are intended to be used in the gluten free diet of CD patients. Moreover the new method can also be used for the screening of cereals and different wheat varieties for the level of toxicity for CD patients.

  • Patent number: 7964370
    Abstract: An analytical strip and a detecting method using the analytical strip are provided. The analytical strip includes a substrate having a channel thereon. The channel has a first region, a second region and a third region, which are connected sequentially. A first antibody is localized in the first region. A saccharide and a peroxidase are localized in the first or second region.

  • Patent number: 7951545
    Abstract: A method for detecting lysosomal storage diseases including the steps of performing an assay for a single species of glycosaminoglycan contained in a specimen and correlating results of the assay with lysosomal storage diseases. A body fluid such as urine or blood can be employed as a specimen. The assay can be performed by use of a polypeptide that is capable of specifically binding to a glycosaminoglycan-containing molecule. The polypeptide may be an antibody, or a polypeptide having an antigen-binding site of an antibody.

  • Patent number: 7947465
    Abstract: Bodily fluid is analyzed for the presence of drugs of a selected panel of drugs in a simultaneous assay in which sample of the fluid is incubated with additional amounts of all drugs of the panel, antibodies specific to each of the drugs of the panel, and microparticles, the microparticles being divided into subsets, one subset for each drug in the panel and each subset distinguishable from the others. The incubation is performed in a liquid medium in which competitive binding occurs, the drugs in the sample competing with those added to the assay medium for binding to the antibodies. In one procedure, the added drugs are pre-coupled to the microparticles while the antibodies are not, and the incubation is followed by further incubating the microparticles with labeled ligands that have affinity for the antibodies.

  • Patent number: 7947439
    Abstract: The present invention relates to a method of detecting whether a target animal is Bovine Viral Diarrhea Virus (BVDV) positive or negative by determining whether a gp48 protein-specific reagent binds to a gp48 Bovine Viral Diarrhea Virus protein or protein fragment, which retains antigenic specificity, from a target animal's tissue sample.

  • Patent number: 7943334
    Abstract: The present invention provides an immunological detection method that can detect milk allergens, allergens of albumen, flour, buckwheat and peanut with high sensitivity in foods containing these allergens regardless they are denatured/native, and a detection kit to be used therefor. It is a method for detecting allergens by using 2 or more monoclonal antibodies recognizing native and denatured milk allergens, native and denatured albumen allergens, native and denatured flour allergens, native and denatured buckwheat allergens, and native and denatured peanut allergens, using asl casein which is the main protein of milk casein, ?-lactoglobulin which is the main protein of whey, ovalubumin and ovomucoid which are main proteins of albumen, gliadin which is the main protein of flour, protein with a molecular weight of 24 kDa and 76 kDa which are main proteins of buckwheat, and Ara h1 which is the main protein of peanut as an index.

  • Patent number: 7939282
    Abstract: Compositions and methods for detecting sepsis by contacting a subject-derived sample with a ligand that binds to GRK and determining the concentration of GRK in the sample. An increase in the concentration of GRK compared to that of a normal, healthy control sample indicates that the subject from which the sample is obtained is suffering from or at risk of developing sepsis.

  • Patent number: 7919255
    Abstract: A means of measuring and monitoring skeletal growth rate using a plasma analyte, amino-terminal C-type natriuretic peptide (NT-CNP). Plasma NT-CNP concentrations reflect the potential for further growth of the immature skeleton. Measurement of plasma NT-CNP in a subject, when related to the mean of an appropriate age and gender matched set of control subjects, provides an index of the severity of a growth disorder not otherwise available and facilitates diagnosis in children with undetected osteo-chondrodysplasias or other intrinsic disorders of the growth plate. The invention also provides a means of detecting and monitoring potentially harmful effects of drugs and other factors on skeletal growth long before they are evident using current methods in clinical practice.

  • Publication number: 20110076703
    Abstract: A method of determining the concentration of at least one analyte in a plurality of samples by sequentially subjecting each sample to an analysis cycle comprises contacting the sample or a sample-derived solution with a sensor surface supporting a species capable of specifically binding the analyte or an analyte-binding species, detecting the amount of binding to the sensor surface, and regenerating the sensor surface to prepare it for the next analytical cycle, and based on the detected binding to the sensor surface determining the concentration of analyte in each sample using virtual calibration data calculated for each analysis cycle from real calibration data obtained by contacting the solid phase with samples containing known concentrations of analyte.
