Abstract: In one embodiment, the invention provides a method of diagnosing sepsis or a virus-related infection (often a viral hemorrhagic fever infection) in a subject by detecting and measuring the level of a set of sepsis and virus infection-associated-GTPase biomarkers in a sample obtained from the subject using multiplexed flow cytometry. Related kits are also provided. In a preferred embodiment, the invention provides point of care diagnostic methods for determining an early stage sepsis or the severity of a virus infection, especially in a hospital or other setting.

Abstract: The present invention relates generally to glutathione derivatized beads which are adapted for use in conjunction with glutathione-S-transferase fusion proteins (generally, GST fusion proteins, which contain a fluorescent label such as fluorescent green protein) for use in flow cytometry. The present invention also relates to methods for detecting and/or quantifying interactions between a GST fusion protein and their binding partners, in particular, labeled binding partners such as fluorescently labeled binding partners. By creating glutathione beads with an appropriate high or increased site density, disadvantages often associated with low affinity systems and quick off-rates in solution may be resolved to provide a workable system and method. Methods of identifying potential agonists, antagonists and regulator compounds of proteins fused to GST from libraries of compounds represents another aspect of the present invention.

Abstract: The present invention provides a general approach for G protein coupled receptors that may be used to define agonists and antagonists, and the specificity of receptor coupling to G protein subunits. Methods of the present invention use small volumes (microliters) and are compatible with high throughput flow cytometry. When assays of the present invention are multiplexed, the specificity of the interactions of a receptor with many G proteins may be determined simultaneously.
