    摘要: Described herein are methods of detecting a wound infection and for detecting the presence or absence of bacteria, for example, wound bacteria in a sample, by contacting a sample with a peptide substrate derived from the modification of the reactive site loop (RSL) domain of the α1-proteinase inhibitor. In the current invention, we have demonstrated that these peptide substrates without the alpha 1 protein can be efficiently used as peptide substrates. The modification or the absence of modification of this peptide substrate by the enzyme produced and/or secreted by the bacteria, can serve as an indicator for the presence or absence of the bacteria in the sample. The present invention also features a biosensor for detecting the presence or absence of bacteria in a sample.

    摘要: The present invention provides a protein-based biomarker, Protein C Inhibitor (PCI) that is useful in qualifying prostate cancer status in a patient. In particular, the biomarker of this invention is useful to classify a subject sample as prostate cancer or non-prostate cancer. The biomarker can be detected by SELDI mass spectrometry.

    摘要: Disclosed herein is a high-throughput assay to measure intracellular polyglutamine protein aggregation using fluorescence resonance energy transfer (FRET). Three libraries of over 3000 biologically active small molecules were screened for inhibitory activity, and a lead compound was characterized in detail. Y-27632, an inhibitor of the Rho-associated kinase p160ROCK, diminished polyglutamine protein aggregation at micromolar concentrations, and reduced neurodegeneration in a Drosophila model of polyglutamine disease.

    摘要: Coagulation and fibrinolysis assays and related compositions, systems, methods, and kits are provided. In some embodiments, a coagulation and fibrinolysis assay may utilize one or more biological molecules. For instance, the assay may comprise combining a blood or blood-derived patient sample with the biological molecule(s) and measuring one or more properties of the sample associated with coagulation and/or fibrinolysis. The biological molecules may serve to shorten the assay duration and/or enhance the sensitivity of the assay relative to certain conventional assays. In certain embodiments, the biological molecules may allow pathological coagulation and/or fibrinolysis phenotypes to be elucidated. The coagulation and fibrinolysis assays described herein may be used for a wide variety of clinical and/or laboratory applications, including the diagnosis of certain coagulation and/or fibrinolysis disorders, such as trauma-induced coagulopathy and hyperfibrinolysis.
