  • Patent number: 7754436
    Abstract: Heart and brain fatty acid binding proteins (H-FABP, B-FABP) are markers for stroke. The invention provides a diagnostic assay for either of these markers, preferably by ELISA using a anti-H-FABP or B-FABP antibody. Since H-FABP is also a marker for acute myocardial infarction (AMI), to distinguish stroke from AMI requires an assay specific to AMI, e.g. using troponin-1 or CK-MB as a marker, also to be carried out.

  • Patent number: 7611855
    Abstract: Using two types of antibodies, i.e., a first antibody having a higher affinity for a target substance than for a competitive substance and a second antibody having a higher affinity for the competitive substance than for the target substance, a specimen is treated with these two antibodies. Then, the competitive substance in the specimen first binds to the second antibody and thus the ratio of the target substance to the competitive substance in the specimen is enlarged. As a result, the target substance becomes liable to bind to the first antibody and, in its turn, the reactivity of the target substance is elevated compared with the case of using the first antibody alone. Thus, the target substance in the specimen can be accurately assayed while avoiding the effects of the competitive substance contained in the specimen.

    Abstract: A method having clinically sufficient degree of diagnostic accuracy for detecting the presence of coronary artery disease in a human patient from the general population and for distinguishing between the stages of the disease in that patient is disclosed. The stages are, first, the non-acute stage, which is either asymptomatic coronary artery disease or stable angina, second, the acute stage known as unstable angina, and, third, the acute stage known as acute myocardial infarction. The diseased state (as opposed to the non-diseased state) is indicated by the clinically significant presence of a first marker in a sample from the patient. The presence of one of the two acute stages, unstable angina or acute myocardial infarction, is indicated by the clinically significant presence of a second marker in a sample from the patient. The presence of the more severe acute stage known as acute myocardial infarction is indicated by the clinically significant presence of a third marker in a sample from the patient.

  • Patent number: 7569675
    Abstract: A lagomorph derived monoclonal antibody for recognizing the progesterone receptor (PR) (clone SP2) with immunohistochemistry and methods for creating such an antibody are disclosed. No need of target retrieval in immunohistochemistry is their prominent advantage compared to currently available PR antibody. Furthermore, the very low background when the lagomorph derived monoclonal antibody is used in immunohistochemistry is also impressive. The immunohistochemistry comparative study with about fifty clinical specimens showed that the new PR antibody (clone SP2) antibody had favorable results when compared to mouse monoclonal antibody PR (clone 1A6), the best one in the current market. The PR antibody may prove of great value in the assessment of PR status in human breast cancer. Humanized versions of the PR antibody may provide therapeutic benefits.

  • Patent number: 7550288
    Abstract: A biochemical analysis unit has a flow-through area in which plural spot areas are arranged, and probes are spotted onto the spot areas. The biochemical analysis unit is set into a chamber of a reaction vessel. A reaction solution containing a target is supplied through an inlet into the chamber. A flow rate is adjusted such that the pressure loss may be 80 kPa when the reaction solution flows through the flow-through area. When the pressure loss is increased, the reaction solution flows through the flow-through area after equivalently spreading into a lower side of the chamber. Thus the flowing speed is decreased.

  • Patent number: 7541159
    Abstract: Antibodies have been developed against the different molecular forms of urokinase using synthetic peptides as immunogens. The peptides were synthesized specifically to represent those regions of the urokinase molecules which are exposed in the three-dimensional configuration of the molecule and are uniquely homologous to urokinase. Antibodies are directed against the lysine 158-isoleucine 159 peptide bond which is cleaved during activation from the single-chain (ScuPA) form to the bioactive double chain (54 KDa and 33 KDa) forms of urokinase and against the lysine 135 lysine 136 bond that is cleaved in the process of removing the alpha-chain from the 54 KDa form to produce the 33 KDa form of urokinase. These antibodies enable the direct measurement of the different molecular forms of urokinase from small samples of conditioned medium harvested from cell cultures.

Polyclonal antibodies (PAb) to specific amino acid sequences were subsequently purified from goat serum by sequential affinity purification. Monoclonal antibodies were raised against specific polypeptides. Recombinant human NT-proBNP (or rhNT-proBNP) was expressed and purified in order to obtain material for use in calibration of a quantitative method for measurement of human NT-proBNP.

  • Patent number: 7439025
    Abstract: Antibodies are described, which are suitable for identification of ?-carboxyglutamic acid (Gla), said antibodies having an ability of identifying Gla residues in proteins and/or peptides, while not reacting with glutamic (Glu) residues in corresponding proteins and/or peptides. Methods for the preparation and identification of said antibodies as well as methods for detection of Gla in biological fluids, tissue extracts, tissue specimens, in which methods said antibodies are used, are also described. There is also described the use of said antibodies for immunopurification of Gla-containing proteins or peptides by, for instance, immunoprecipitation or immunoaffinity chromatography.

  • Patent number: 7410771
    Abstract: A reagent and method for the specific and highly sensitive detection of C. parvum in which the reagent is an antibody for a soluble C. parvum sporozoite antigen and the method is an immunoassay in which the antibody is used to detect or quantify C. parvum sporozoite antigen in a sample. The sample is treated to cause excystation of C. parvum oocytes, thereby releasing a C. parvum sporozoite antigen, and combined with antibodies specific for the sporozoite antigen under conditions to form an antibody-antigen complex. Detection of the complex indicates the presence of C. parvum in the sample. The assay allows recognition and detection of C. parvum in turbid samples, and due to a lack of crossreactivity with other Cryptosporidium species, is specific for C. parvum contamination or infection. The assay is highly sensitive, allowing for the detection of less than 100 oocysts per milliliter of sample.

  • Patent number: 7410768
    Abstract: A method and test device for differentiating between states of an analyte that can exist in different forms, such as follicle stimulating hormone (FSH). The method or test device uses a pair of specific binding agents, especially monoclonal antibodies, in two assays for the same analyte. The assays, applied to contemporaneous samples, differ from one another in format, one being a two step assay and the other being one step. A novel pair of anti-FSH monoclonal antibodies that can be used together in two such assays to differentiate pre-menopausal and post-menopausal FSH samples is disclosed.
