摘要： The present invention is directed to methods and compositions for an allosteric enzyme coupled assay, and preferably to an allosteric enzyme coupled immunoassay (AECIA). The assay uses an allosteric enzyme to generate a readout signal. The assay is based on the competition between an analyte in a sample and an analyte or analyte analog conjugated to an allosteric regulator with a specific binding reagent for the analyte. In the absence of any analyte in the sample, an analyte or an analyte analog conjugated to an allosteric regulator binds to the specific binding reagent and such binding prevents or reduces the allosteric regulator's regulation, e.g., activation, on the allosteric enzyme. An analyte, if present in the sample, competes with the analyte or analyte analog conjugated to the allosteric regulator for binding with the specific binding reagent, reduces or prevents binding of the specific binding reagent to the analyte or analyte analog conjugated to the allosteric regulator, leading to increased regulation, e.g., activation, of the enzyme. 1-substituted-(3-D-fructofuranose 2, 6bisphosphate compounds and conjugates comprising the same are provided. Kits comprising the conjugates, and methods using the conjugates for assaying an analyte are further provided.

摘要： The present invention provides a method for assaying alpha-methylacyl-CoA racemase activity. In the assay, a sample containing an alpha-methylacyl-CoA racemase or suspected of containing an alpha-methylacyl-CoA racemase is contacted with (2R)-2-methylacyl-CoA. If alpha-methylacyl-CoA racemase is present in the sample (2R)-2-methylacyl-CoA is converted into (2S)-methylacyl-CoA. The method then utilizes a cycling reaction system between (2S)-methylacyl-CoA and trans-2,3-dehydroacyl-CoA to generate a detectable signal that corresponds to the alpha-methylacyl-CoA racemase activity. Kits for assaying alpha-methylacyl-CoA racemase based on the same principle are also provided.

摘要： The present invention provides a method for assaying myeloperoxidase activity. In the assay, a sample containing myeloperoxidase or suspected of containing myeloperoxidase is contacted with substrate including serine, hydrogen peroxide, and a halide. If myeloperoxidase is present in the sample, serine is converted into glycolaldehyde, which is further converted into glycolate by a glycoaldehyde converting enzyme (e.g. glycolaldehyde dehydrogenase) (1.2.1.21). The method then utilizes a cycling reaction system between glycolate and glyoxylate to generate a detectable signal that corresponds to the myeloperoxidase activity. Kits for assaying myeloperoxidases based on the same principle are also provided.

摘要： The present invention provides a two-step assay for measuring myeloperoxidase (MPO) activity in a blood sample. The first step utilizes a chromogenic substrate to measure first peroxidase activity including MPO activity in the sample, whereas the second step measures non-MPO peroxidase activity in the presence of the same chromogenic substrate and a specific MPO inhibitor. Specific MPO peroxidase activity is then determined by comparing the non- MPO peroxidase activity and the total peroxidase activity. The MPO peroxidase activity obtained in this fashion may be proportional, and preferably directly proportional, to the mass of MPO in the sample. Kits for assaying MPO peroxidase activity based on the same principle are also provided.
