US Patent:

8318450, Nov 27, 2012
Filed:

Jun 22, 2011
Appl. No.:

13/166627
Inventors:

Schuyler Corry - Eugene OR, US
William Downey - Eugene OR, US
Brian Filanoski - Spokane Valley WA, US
Kyle Gee - Springfield OR, US
Lawrence Greenfield - Eugene OR, US
James Hirsch - Springfield OR, US
Iain Johnson - Eugene OR, US
Aleksey Rukavishnikov - Eugene OR, US
Assignee:

Life Technologies Corporation - Carlsbad CA
International Classification:

C12Q 1/34
US Classification:

435 18, 435227, 435231
Abstract:

The present invention relates to compounds that are substrates for an enzyme, and upon reaction with the enzyme provide a detectable response, such as an optically detectable response. In particular, the compounds have utility in detecting the presence of a β-lactamase in a sample. In addition to the compounds, methods are disclosed for analyzing a sample for the presence of a β-lactmase, for example, as an indicator of expression of a nucleic acid sequence including a sequence coding for a β-lactmase. Kits are disclosed that include the disclosed compounds and additional components, for example, cells, antibodies, a β-lactmase or instructions for using the components in an assay.

US Patent:

20050233307, Oct 20, 2005
Filed:

Sep 12, 2003
Appl. No.:

10/661451
Inventors:

Kyle Gee - Springfield OR, US
Courtenay Hart - Eugene OR, US
Wai-Yee Leung - Eugene OR, US
Wayne Patton - Eugene OR, US
Aleksey Rukavishnikov - Eugene OR, US
Richard Haugland - Eugene OR, US
Zhenjun Diwu - Sunnyvale CA, US
International Classification:

C12Q001/00
G01N033/00
US Classification:

435004000, 436086000
Abstract:

The present invention provides methods and fluorescent compounds that facilitate detecting and labeling of a fusion protein by being capable of selectively binding to an affinity tag. The fluorescent compounds have the general formula A(B)n, wherein A is a fluorophore, B is a binding domain that is a charged chemical moiety, a protein or fragment thereof and n is an integer from 1-6 with the proviso that the protein or fragment thereof not be an antibody or generated from an antibody. The present invention provides specific fluorescent compounds and methods used to detect and label fusion proteins that contain a poly-histidine affinity tag. These compounds have the general formula A(L)m(B)n wherein A is a fluorophore, L is a linker, B is an acetic acid binding domain, m is an integer from 1 to 4 and n is an integer from 1 to 6. The acetic acid groups interact directly with the positively charged histidine residues of the affinity tag to effectively label and detect a fusion protein containing such an affinity tag when present in an acidic or neutral environment.
