Enriched Antibody For Detecting Mycobacterial Infection, Methods Of Use And Diagnostic Test Employing Same

View page
US Patent:
7335480, Feb 26, 2008
Filed:
Jul 20, 2005
Appl. No.:
11/186933
Inventors:
Vladimir A. Koulchin - Portland ME, US
Elena V. Molokova - Portland ME, US
Jill L. Kerrick - Scarborough ME, US
Assignee:
Chemogen, Inc. - South Portland ME
International Classification:
G01N 33/53
A61K 39/04
US Classification:
435 71, 435 4, 435 72, 435 732, 435 79, 435 792, 424 91, 424 92, 4241301, 4241641, 4241681, 4241841, 4242341, 4242481
Abstract:
The disclosed technology provides an enriched antibody population, highly specific for an antigen of a surface polysaccharide, from a mycobacterium. In a related embodiment, the antibody is enriched by having been raised in an environment that maintains antigenically active antigen. These antibodies may be used in an immunoreactive environment for detecting the presence of a mycobacterial infection in a sample from a subject.

US Patent:
20050148039, Jul 7, 2005
Filed:
Nov 16, 2004
Appl. No.:
10/989050
Inventors:
Norman Moore - North Berwick ME, US
Mary Fent - Cumberland Center ME, US
Vladimir Koulchin - Portland ME, US
Elena Molokova - Portland ME, US
International Classification:
C07K016/12
G01N033/554
G01N033/569
C08B037/00
US Classification:
435007320, 530388400, 536053000
Abstract:
Disclosed is a cell wall C-polysaccharide antigen of which contains not more than 10% by weight of protein, and preferably less which has been purified with 0.1 N Na OH prior to deproteinizing. Also disclosed are polyvalent antibodies raised against which have been affinity purified by passing them over a chromatographic affinity matrix to which is coupled the purified and at least partially deproteinized antigen to render them antigen-specific.

US Patent:
20080096236, Apr 24, 2008
Filed:
Jun 11, 2007
Appl. No.:
11/761255
Inventors:
Vladimir Koulchin - Portland ME, US
Norman Moore - North Berwick ME, US
Elena Molokova - Portland ME, US
Mary Fent - Cumberland Center ME, US
Assignee:
Binax, Inc. - Portland ME
International Classification:
G01N 33/569
C07K 16/12
C12P 19/00
US Classification:
435007320, 435072000, 530389500
Abstract:
A process is disclosed for separating a carbohydrate antigen from a Gram-positive or Gram-negative bacteria in a purified form that contains no more than 10% protein. The separated antigen is coupled to an affinity column, over which polyclonal antibodies to the same bacteria are chromatographed and recovered in a purified form that exhibits high specificity and sensitivity in immunoassays for the raw carbohydrate antigen corresponding to the purified antigen on the column. A particularly preferred form of rapid immunochromatographic assay employing the purified antibodies, which assay is very useful as an aid to rapid diagnosis of diseases caused by bacteria, is disclosed.
