Filed:

Aug 21, 1997

Appl. No.:

8/917012

Inventors:

Douglas D. Hansmann - Libertyville IL
John P. Grace - Lake Villa IL
Michael G. Lowery - Wildwood IL
Gary M. Oosta - Gurnee IL
Neil W. Loomis - Racine WI
Eric B. Shain - Glencoe IL

Assignee:

Abbott Laboratories - Abbott Park IL

International Classification:

G01N 33543

US Classification:

435 6

Abstract:

The present invention relates to analytical devices for determining the presence or amount of an analyte in a test sample. The analytical devices comprise an inlet port, a vent, a channel, and an array of structures. The structures have immobilized reagent covalently or non-covalently attached to the surface of the structures. The immobilized reagent captures analyte in the test sample where it is detected by a detection system. The present invention also provides methods and reagents for performing assays utilizing the analytical devices of the present invention. The present invention also provides methods of manufacturing the analytical devices of the present invention.

Filed:

Nov 15, 1993

Appl. No.:

8/153136

Inventors:

John A. Grace - Hinsdale IL

International Classification:

G06F 1730

US Classification:

395600

Abstract:

A method and apparatus is provided for generating structured query language instructions for communication to a database. In response to receipt of user-supplied input dimensions, an output table is automatically selected that represents the user's query of the relational database. The system automatically identifies and generates the links between data in predefined data tables within the database and the automatically selected output table. From the output table and data links, structured query language instructions are automatically generated. A technique is included to select the minimum number of tables reflective of the input dimensions. Each link between the input data tables and the output table is checked bi-directionally to ensure the integrity of the table selected.
