Patent number: 8404493Abstract: Methods for measuring the amount of two or more analytes of interest in a fluid sample, and kits useful in the methods, are disclosed. The methods involve determining a ratio of a detected amount of a single analyte of interest, to the sum of a detected amount of each of the analytes of interest plus a detected amount of a control, wherein the amount of each analyte of interest is directly or inversely related to the ratio for each analyte of interest.Type: GrantFiled: June 4, 2009Date of Patent: March 26, 2013Assignee: Response Biomedical CorporationInventors: Whalley K. Fong, Paul C. Harris, Brian G. Richards

Patent number: 8318420Abstract: Methods of increasing specific binding, decreasing non-specific binding, and reducing false-positive interaction in solid phase assays for influenza are disclosed. In the methods, the solid phase apparatus (lateral flow solid phase apparatus or capillary flow solid phase apparatus) is subjected to elevated heat subsequent to application of a test sample to the solid phase apparatus.Type: GrantFiled: July 12, 2010Date of Patent: November 27, 2012Assignee: Response Biomedical CorporationInventors: Whalley K. Fong, Paul C. Harris

Patent number: 8192943Abstract: Methods for quantitatively measuring the amount of an analyte of interest in a fluid sample, and kits useful in the methods, are disclosed. The methods comprise sandwich assays, and utilize an internal calibration reaction that closely mimics the reaction of test particles by the use of a two-step reaction.Type: GrantFiled: December 21, 2009Date of Patent: June 5, 2012Assignee: Response Biomedical CorporationInventors: Paul C. Harris, Whalley K. Fong, Lynn Cloney

Patent number: 7691595Abstract: Methods for quantitatively measuring the amount of an analyte of interest in a fluid sample, and kits useful in the methods, are disclosed. The methods involve providing a solid phase apparatus comprising a membrane having an application point, a sample capture zone, and a control capture zone, where the sample capture region is between the application point and the control capture zone; and providing a sample collection apparatus comprising a population of analyte binding particles or a population of analyte coated particles. In the assays, a fluid sample is introduced into the sample collection apparatus, and the resultant mixture is applied to the application point of the membrane. The fluid allows transport components of the assay by capillary action to and through the sample capture zone and subsequently to and through the control capture zone. The amount of analyte in the fluid sample is related (e.g.Type: GrantFiled: November 21, 2006Date of Patent: April 6, 2010Assignee: Response Biomedical CorporationInventor: Whalley K. Fong
