Filed:

Jun 3, 2003

Appl. No.:

10/453032

Inventors:

Craig Adams - Corona CA, US
Patty Pang - Rancho Cucamonga CA, US
C. Belei - Anaheim CA, US

Assignee:

Beckman Coulter, Inc.

International Classification:

G01N033/53
G01N033/554
G01N033/569
A61K039/02
C12N009/22

US Classification:

435/007100, 435/007320, 435/199000, 424/190100

Abstract:

The gene for DNase B has been cloned and vectors incorporating the cloned DNA have been used to transform allowing efficient and rapid production of the DNase in without the necessity of growing large quantities of The enzyme can be produced with a leader peptide at its amino terminus. An improved method for the purification of naturally occurring DNase B enzyme is also provided. The DNase B enzyme produced, either by purification of naturally occurring enzyme or by recombinant DNA techniques, can be used to generate antibodies and can also be used in immunochemical assays to detect the presence of anti-DNase B antibodies in serum as a marker of infection by

US Patent:

Filed:

Sep 13, 2013

Appl. No.:

14/026358

Inventors:

Yagang Liu - Yorba Linda CA, US
Patty Pang - Brea CA, US
Brian Peterson - Ontario CA, US

Assignee:

Beckman Coulter, Inc. - Brea CA

International Classification:

G01N 21/01

US Classification:

356246

Abstract:

An analytical system is disclosed. The analytical system includes a storage container configured to store a plurality of capillaries. It also includes a gripper configured to receive at least one of the plurality of capillaries, and move the at least one capillary so that an end of the capillary contacts a sample in a sample container and draws the sample in the capillary. The system also includes a reader configured to detect a signal from the sample in the capillary.
