Combining Transmittance Detection And Chromatographic Strip Techniques For Quantification Of Analyte In Biological Fluids

View page
US Patent:
7186566, Mar 6, 2007
Filed:
Jul 28, 2003
Appl. No.:
10/628670
Inventors:
Suyue Qian - Fremont CA, US
International Classification:
G01N 33/551
US Classification:
436524, 436518, 436527, 436164, 436169, 422 50, 422 55, 422 56, 422 61, 422 681, 435 71, 4352831, 4352871, 4352872, 4352877, 4352887
Abstract:
Chromatographic strip is used in combination with a transmittance detecting system in a test to quantitate analytes in biological fluid. Chemical reagents or conjugate labels are simply absorbed on the passages' materials of the strip. The substrates, affinity reagents, or antibodies are immobilized on transparent beads in the detection cell of the strip. The biological fluid passes through the strip. The captured analytes are detected by transmittance detection for quantification. Uncaptured elements and interferences in the fluid are drained to the absorbent portion of the strip when the fluid passes the cell as a wash. This chromatographic strip with an analyte capture zone simplifies the procedures that a transmittance detecting system alone cannot overcome. Adjustable light path of the cells in the strip overcome the sensitivity limitation of reflectance detection.

Automated Immunoassay Cassette, Apparatus And Method

View page
US Patent:
7238519, Jul 3, 2007
Filed:
Dec 17, 2004
Appl. No.:
11/016016
Inventors:
Neal F. Bellet - Walnut Creek CA, US
Jeffrey Shindelman - Castro Valley CA, US
Thomas E. Worthy - Walnut Creek CA, US
Kimberly Haley - Belmont CA, US
Richard K-T Lee - Fremont CA, US
Jane Eunhee Kyung - Sunnyvale CA, US
Suyue Qian - Fremont CA, US
Assignee:
Cholestech Corporation - Hayward CA
International Classification:
C12M 1/34
US Classification:
4352872, 422 56, 422 57, 422 58, 4352877, 4352879, 435805, 435810, 435970, 436514, 436518, 436810
Abstract:
An immunoassay cassette, apparatus, and method for detecting an analyte in a liquid body-fluid sample are disclosed. The cassette has a body and a support mounted on the body, for movement relative to the body to first and second transfer positions. Sample supplied to a sample well in the cassette body is transferred to a reagent reservoir on the cassette body, by moving the support to its first transfer position. Here the sample reacts with a first reagent composition in the reservoir effective to form a modified sample. The modified sample is then transferred to a reagent strip on the support by moving the support to its second transfer position. The reagent strip has a transfer zone at which sample material is transferred to the strip, a second reagent composition effective to react with the modified sample to form a detectable analyte-dependent product, and a detection zone located downstream at which the detectable product can be observed. By controlling movement of the support to its first and second positions, the cassette can effectively handle a variety of samples having different flow rates.
