  • Patent number: 8822229
    Abstract: The inventions provides a method for immunologically determining a keratan sulfate level which method includes bringing an anti-keratan sulfate monoclonal antibody into contact with a biological sample, the anti-keratan sulfate monoclonal antibody exhibiting a relative reaction specificity between keratan sulfate-I and keratan sulfate-II represented by IC50KS-I/KS-II of 0.4 to 5, to thereby provide a signal; and detecting keratan sulfate contained in the biological sample from the signal. On the basis of the method, the invention also provides a joint disease detection method and a method for assessing the effect of a remedy for a joint disease and a candidate substance therefor. Through these methods, a very small amount of keratan sulfate contained in a sample, can be determined. Particularly, these methods can determine, at high-sensitivity and high-specificity, the total keratan sulfate including keratan sulfate-I, which have been difficult to determine through a conventional technique.

  • Patent number: 7964360
    Abstract: The invention relates to methods for determining the progression of cartilage degeneration diseases, such as osteoarthritis and rheumatoid arthritis, by quantitating collagen synthesis and degradation markers in patient samples. One can determine whether a cartilage degeneration condition is progressing, regressing, or remaining stable by quantitating collagen synthesis and degradation markers in patient samples and comparing the value obtained to a reference value. When a joint affected by cartilage degeneration in question expresses collagen synthesis and degradation markers, a change in this value is indicative of a change in the progression of the cartilage degeneration condition. The methods and apparatus of the invention allow accurate determination of the therapeutic effects certain cartilage degeneration drug treatments, including osteoarthritis and rheumatoid arthritis drug treatments, so are also useful for pharmaceutical efficacy studies in mammals.

  • Patent number: 5786154
    Abstract: The invention provides methods for detecting elevated levels of phospholipase A.sub.2 activating protein in persons suspected of having rheumatoid arthritis to thereby indicate the presence of rheumatoid arthritis in the person comprising the steps of providing a sample of body fluid or tissue from said person; contacting the sample with an antibody specific for phospholipase A.sub.2 activating protein such that the antibody binds with phospholipase A.sub.2 activating protein in the sample; detecting the antibody thereby indicating the presence of phospholipase A.sub.2 activating protein, whereby elevated levels of phospholipase A.sub.2 activating protein in the sample as compared with levels found in persons not having rheumatoid arthritis indicates the presence of rheumatoid arthritis in the person. Kits and reagents for detecting rheumatoid arthritis are also provided.

  • Patent number: 5776708
    Abstract: The invention relates to a method for identifying T cell populations involved in autoimmune diseases. This involves determining levels of a V.beta. element in a body fluid sample of a patient and comparing this to normal levels. Variation from normal levels is indicative of an autoimmune disease. The invention also involves assaying T cell subpopulations in a sample to determine clonality of .beta. chains. Clonality can also be used to diagnose autoimmune disorders.

  • Patent number: 5747266
    Abstract: An assay and method for screening newborns to determine risk of Sudden Infant Syndrome is described. The assay and method is based on the detection of elevated IgM-anti-IgG (MAG) levels in newborns' serum within the first year of birth. In particular, it has been discovered that elevated MAG levels indicate an increased risk of Sudden Infant Death Syndrome (SIDS).

  • Patent number: 5698393
    Abstract: A method for treating biological samples, e.g., human sera or plasma, suspected of containing rheumatoid factors to eliminate cross-reactivity and false positive assay results in IgM immunoassays that are caused by the presence of rheumatoid factors in these biological samples. In one aspect, the method comprises diluting a biological sample with a sufficient amount of rheumatoid factor neutralization buffer to cause the pH of resulting reaction mixtures containing this sample and a solid phase material to be sufficiently low to cause rheumatoid factors in those mixtures to reduce their affinity to IgG antibodies to such an extent that they will not form a complex with IgG antibodies bound to the solid phase material, thereby facilitating the removal of these rheumatoid factors from the mixtures prior to the detection phase of a diagnostic assay.

  • Patent number: 5556745
    Abstract: The invention is a simple and rapid method for immune complex dissociation and destruction of rheumatoid factors. It permits the quantitative measurement of the total, i.e., free and immune complex-bound, antigen contained in a test sample. The method involves heating the test sample to a point sufficiently above 65.degree. C. at which the antigen-binding function of antibodies is destroyed. As a consequence, interference by rheumatoid factors is eliminated and the antigen is released from immune complexes, after which it can be measured in an antigen assay that recognizes the heat-denatured antigen.

  • Patent number: 5556759
    Abstract: An assay and method for screening newborns to determine risk of Sudden Infant Syndrome is described. The assay and method is based on the detection of elevated IgM-anti-IgG (MAG) levels in newborns' serum within the first year of birth. In particular, it has been discovered that elevated MAG levels indicate an increased risk of Sudden Infant Death Syndrome (SIDS).In a preferred embodiment of the invention, an ELISA is utilized in which a first binding agent having specific affinity for IgM is used to capture and separate IgM antibodies from the newborn's blood sample. A second binding agent having specific affinity for IgG which has been separated from the sample eluant by complexing with MAG, is then used in conjunction with an enzyme conjugate to indirectly determine the amount of MAG in the newborn's blood. The MAG level is then compared to a cut-off which is selected to separate out approximately 4% of the newborns which have the highest MAG levels.

  • Patent number: 5496520
    Abstract: A rotary fluid manipulator utilizable as a diagnostic device includes a porous body having fluid passages defined therein by fluid blocking means in the porosities of the body such as openings or slots in the body or compaction of areas of the porous body to define fluid passages therebetween. Various substances or binding partners such as receptors, immunoassay or other assay test materials and test specimens can be deposited on the porous body to permit various types of tests to be made by rotation of the manipulator to cause conjunctive centrifugal and wicking induced flow of fluids deposited thereupon.

  • Patent number: 5472849
    Abstract: A method for the detection of the presence of inflammation in a patient by measuring the amount of circulating intercellular adhesion molecule (cICAM-1) in a sample of one or more bodily fluids of the patient and then comparing the amount of cICAM-1 in the sample to standards normal for the bodily fluid or fluids assayed. The amount of cICAM-1 can be measured using anti-ICAM-1 antibodies. Higher than normal amounts of cICAM-1 indicate the presence of inflammation.
