Abstract:
The present invention relates generally to chemical and biological decontamination solutions and methods of using them. The invention is useful for decontaminating and/or disinfecting a wide range of compounds and organisms. In particular, the systems, methods, solutions, and formulations of the invention can be used to remove and/or neutralize organophosphates, mustard agents, and other toxic chemicals, bacteria, bacterial spores, fungi, molds and viruses.
Abstract:
The present invention provides novel fluorescent compounds and covalent attachment chemistries which facilitate the use of these compounds as labels for ultrasensitive and quantitative fluorescent detection of low levels of biomolecules. In a preferred embodiment, the fluorescent labels of this invention are novel derivatives of the hydroxy-pyrene trisulphonic and disulphonic acids which may be used in any assay in which radioisotopes, colored dyes or other fluorescent molecules are currently used. Thus, for example, any assay using labeled antibodies, proteins, oligonucleotides or lipids, including fluorescent cell sorting, fluorescence microscopy (including dark-field microscopy), fluorescence polarization assays, ligand, receptor binding assays, receptor activation assays and diagnostic assays can benefit from use of the compounds disclosed herein.

Abstract:
Novel chemistries, methods and assays are described for the rapid detection and measurement of phosphorylation or de-phosphorylation of polypeptides, oligonucleotides or lipids based upon the use of phosphoryl, phosphoroamino or phosphorothioate specific hetero-bifunctional linkers combined with fluorescence polarization or fluorogenic detection. Homogeneous assay applications possible using these novel chemistries and methods include in vitro fluorescence polarization assays for the detection of general and isoform specific polypeptide, oligonucleotide and lipid kinase and phosphatase enzymes. Heterogeneous assay applications possible using the same novel chemistries and assaymethods enable development of in vitro and in vivo fluorogenic assays of general or specific kinase or phosphatase enzyme activities in cell lysates or serum. In all cases, these new chemistries, methods and assays enable simultaneous multi-kinase detection and profiling.

Abstract:
A fluorescence spectrophotometer system may be implemented in scanning fluorescence polarization detection applications. A wavelength and area scanning fluorescence spectrophotometer system may include a light source, an excitation double monochromator, an excitation/emission light transfer module, an emission double monochromator, a high speed timer-counter circuit board, a precision positioning apparatus for positioning a sample relative to the focal plane of the excitation light, and polarizing filters at the excitation side and the emission side. The system may be operative to analyze more than one fluorescent compound in the sample; additionally or alternatively, the system enables analysis of samples from selected ones of a plurality of samples.
