Filed:

Mar 30, 2001

Appl. No.:

09/823077

Inventors:

Jian Zheng - Raritan NJ, US

Assignee:

Ortho-Clinical Diagnostics, Inc. - Rochester NY

International Classification:

C07K 14/02

US Classification:

435 5, 530820, 530826, 530806, 530350, 4241851, 4241861, 4241891, 536 231, 536 237, 536 2372

Abstract:

We isolated and characterized a new surface mutant of the hepatitis B virus surface antigen (HBsAg). The mutant was isolated from a symptomatic patient with Down's syndrome who was found to be persistently positive for both for HBsAg and anti-HBs Antibody (Ab) with an equally long-lasting anti-HB core (c) IgM Ab.

Assignee:

Ortho-Clinical Diagnostics, Inc. - Rochester NY

International Classification:

G01N 33/68

US Classification:

435 792, 435 693

Abstract:

In the present invention, we described the use of anti-DNA antibody for the detection of prions and diagnosis of Transmissible Spongiform Encephalopathies (TSE) diseases in animals and humans.

US Patent:

Filed:

Sep 19, 2005

Appl. No.:

11/229960

Inventors:

Jian Zheng - Raritan NJ, US

Assignee:

Ortho-Clinical Diagnostics, Inc. - Raritan NJ

International Classification:

G01N 33/543
G01N 33/566

US Classification:

436518, 436501

Abstract:

The aim of the present invention is to provide a non-intrusive way to isolate, concentrate and monitor the TSE disease-related pathogenic prion protein. The invention described several peptides and their ability to capture PrPfrom brain homogenate of prion disease infected animal and human. These eight peptides do not capture cellular prion protein from individual with no prion disease.

International Classification:

H04L 12/28

US Classification:

370254

Abstract:

An address assigning method in a ZigBee network environment formed of a plurality of devices (or nodes), includes: linking the plurality of nodes in a cluster-tree structure; requesting desirable address blocks from a lowest level to a second highest level of the tree ancestor nodes desirable address blocks, respectively; and assigning the desired address blocks to descendents using a top-down procedure.

Jian Zheng - Raritan NJ, US

International Classification:

C12Q 1/70
C07K 14/16
C07H 21/02
C12N 15/867

US Classification:

435005000, 435069300, 435456000, 435325000, 530324000, 530326000, 536023720, 530350000

Abstract:

This invention relates to peptides and their preparation. The peptides each have a sequence that corresponds to the immunodominant region of the HIV-1 group O gp41 envelope protein. The sequence is characterized in that it does not correspond to any known naturally occurring group O sequence or variant. Furthermore, the peptide binds anti-HIV-1 group O antibodies. There are several uses for the peptides, including the detection of antibodies produced in response to HIV-1 group O infection. The peptides may also be incorporated in mosaics and expressed recombinantly.
