Patent number: 11459596Abstract: An apparatus and kit for the detection of ATP in a liquid sample is provided. The apparatus and kit comprise a liquid reagent composition comprising luciferin and a sampling device having a sampling portion and a handling portion. The sampling portion is adapted to acquire and releasably retain a predetermined volume of a liquid sample in one or more cavity that is not substantially defined by space between a plurality of fibers. The sampling device comprises a dry coating that includes an effective amount of a pH-adjusting reagent that, when contacted with a liquid reagent composition having a pH of about 6.8 or lower, changes the pH of the liquid reagent composition to 6.9 or higher. A method of use of the apparatus or kit is also provided.Type: GrantFiled: February 12, 2019Date of Patent: October 4, 2022Assignee: 3M Innovative Properties CompanyInventors: Kenneth R. Davenport, Mark B. Driscoll, Rachel E. Evans, Catherine M. Ramsay, Neil Percy

Patent number: 10196671Abstract: The present invention discloses an assay method for the detection of viable microbial cells in a sample, the assay method comprising the steps of: i) adding an ATP degrading enzyme to a sample suspected of containing viable microbial cells to substantially degrade any extracellular ATP in the sample; ii) adding a phosphate containing compound to the sample to substantially halt action of the ATP degrading enzyme; and iii) subjecting the sample to a detection assay to establish the level of undegraded ATP in the sample to provide an indication of the level of viable microbial cells in the sample.Type: GrantFiled: January 9, 2013Date of Patent: February 5, 2019Assignee: 3M Innovative Properties CompanyInventors: Gerald J. Bugler, Catherine M. Ramsay, Wililam J. Simpson, Mark B. Driscoll
