Abstract: A method is for the detection of presence or absence, quantification, and identification of target microorganisms, such as bacteria, bacterial fragments (e.g., LPS, endotoxin), viruses, fungi as well as other pathogens by means of chemiluminescence. The method include providing a medium with one or more target analytes, target microorganisms or target metabolites, adding a dioxetane compound to the medium so that the dioxetane compound emits light, and detecting the emitted light.

Abstract: Dioxetane compounds represented by Formula I below, and methods of using the dioxetane compounds in the detection of presence or absence, quantification, and identification of microorganisms including bacteria, bacterial fragments (e.g., LPS, endotoxin), viruses, and fungi by means of chemiluminescence.

Abstract: The present invention relates to a method for assessing cell viability of bacterial and fungal cells and to a method for the detection of bacterial and fungal cells with specific enzyme activities. The methods of the present invention rely on the real-time measurement of the level of luminescence signal from a luciferase enzyme directly from a growing culture of bacterial or fungal cells. Furthermore, the present invention relates to a method for assessing susceptibility of bacterial cells to antibiotics by measuring ATP levels using a luciferase assay system.

Abstract: Improved long wavelength-emitting chemiluminescent probes are easy to synthesize and are well-suited for both in vitro and in vivo applications, but are particularly well-suited for in vivo applications. The wavelengths of the emissions of the probes include those in the orange, red or NIR range. Dioxetane compounds and phenolic ester compounds are included.

Abstract: Dioxetane compounds can be used in the detection of presence or absence, quantification and identification of microorganisms including bacteria, bacterial fragments (e.g., LPS, endotoxin), viruses, fungi as well as other pathogens by means of chemiluminescence and to corresponding methods. A method for the detection of a target analyte, a target microorganism or a target metabolite includes providing a medium including one or more target analytes, target microorganisms or target metabolites, adding a dioxetane compound to the medium so that the compound emits light, and detecting the emitted light.
