Patents by Inventor Peter E. Andreotti

Peter E. Andreotti has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6218176
    Abstract: A rapid detection of ATP using dried luciferase/luciferin reagent. A liquid that may include an extraction reagent is applied to the testing surface, such as a counter top. A sampling device having a handle and an absorbent tip is wiped across the testing surface. The absorbent tip absorbs the sample. The sample is then placed in a counting tube. Luciferase/luciferin reagent is immobilized on the absorbent tip of the sampling device or in the bottom of a counting tube. In either case, the liquid rehydrates the luciferase/luciferin reagent allowing ATP present in the sample to react with the luciferase. Light produced by the reaction is measured with a luminometer.
    Type: Grant

  • Patent number: 5916802
    Abstract: A method of taking a sample of an inoculated culture medium and measuring the amount of ATP using a luciferase/luciferin reaction. Additional samples are taken at later time intervals to determine whether anything is growing in the medium. Luciferase/luciferin reagent is immobilized on an absorbent tip of a sampling device in order to stabilize the luciferase/luciferin reagent and to provide a convenient means to combine the luciferase/luciferin reagent with the sample. A counting tube containing an extraction reagent is employed to extract intracellular ATP from the sample. Chlorhexadine diacetate (CDA) is the preferred extraction reagent.
