Patent number: 8202734Abstract: A test device and method for determining the presence or absence of an analyte in a fluid sample, the test device including a support bearing a mark thereon, and a matrix defining an axial flow path. In operation, an observation area in the test device becomes transparent, thereby allowing the user to view a mark that is present on a support that is disposed beneath the observation area. Typically, the mark on the underlying support is configured as a minus (?) sign. In the absence of analyte in the sample, the test device presents a negative result as a minus (?) signal. In the presence of analyte in the sample, however, the mark operates in concert with a perpendicular test line on the observation area to present a positive result as a plus (+) signal that is visible to the user.Type: GrantFiled: April 14, 2009Date of Patent: June 19, 2012Assignee: Quidel CorporationInventors: Jeremy Jerome, Mark Daquipa, Bruce Jacono, Hans Boehringer

Publication number: 20120107956Abstract: Disclosed herein are indirect lateral flow sandwich assays, in which the target analyte binds an analyte-specific reagent comprising a first member of a conjugate pair, forming a complex which contacts and binds a colored particulate label comprising a complementary member of said conjugate pair, forming a second complex. Capture of this analyte-comprising, second complex by an immobilized analyte specific capture reagent results in the formation of an immobilized labeled sandwich complex that can be detected.Type: ApplicationFiled: September 12, 2011Publication date: May 3, 2012Inventors: HANS BOEHRINGER, Mark Daquipa, Fon-Chiu Mia Chen, Hsin Ming Yang, Thomas L. Pisani, Sumitra Nag, Jay Salhaney, Marcella B. Holdridge, Erika Johnston, Jeremy Schonhorn

Patent number: 7491551Abstract: This invention provides solid phase specific binding lateral flow assay methods, devices and kits for quantitating high and low molecular weight analytes. The methods and devices of the invention employ labelled reagents which are either analyte analogs or complementary specific binding pair members for the analyte and a novel arrangement of capture zones comprising immobilized specific binding substances for either the analyte or the labelled reagent to effect bound from unbound labelled reagent as a function of analyte concentration. The capture zones are disposed on a non-bibulous matrix defining a flow path from a sample receiving zone to the capture zone. The devices of this invention also include multilane flow paths and multiple capture zones to quantitate analyte.Type: GrantFiled: November 8, 2006Date of Patent: February 17, 2009Assignee: Quidel CorporationInventors: Hans Boehringer, Gerald Rowley, Allan D.
