Immobilization Method For Producing Active Α-Acid Glycoprotein
View pageUS Patent:
7575908, Aug 18, 2009
Filed:
Apr 11, 2006
Appl. No.:
11/402298
Inventors:
David S. Hage - Hickman NE, US
Hai Xuan - Lincoln NE, US
Hai Xuan - Lincoln NE, US
Assignee:
Board of Regents of the University of Nebraska - Lincoln NE
International Classification:
C07K 17/14
C12N 11/14
C12N 11/14
US Classification:
435174, 530395, 530350
Abstract:
A method and kit for immobilization of a glycoprotein. The method may include activating an affinity support. The affinity support may be activated by reacting the affinity support with a compound that is reactive with one or more functional groups included within the glycoprotein. The method may also include oxidizing the glycoprotein in which oxidation conditions are selected to yield an oxidized glycoprotein that is biologically active and contains a sufficient number of reactive aldehyde groups for coupling to a support. For example, the oxidized glycoprotein may include five reactive aldehyde groups. In addition, the method may include reacting the oxidized-glycoprotein with the activated affinity support to immobilize the glycoprotein.

International Classification:
G01N 33/53
US Classification:
435 71, 435 72, 436518
Abstract:
The present invention is directed to restricted access media (RAM), methods for preparing restricted access media, and kits for preparing restricted access media that contain protected ligand binding agents or protected enzymes. Certain RAM provided contain a plurality of protected regions of the support that contain ligand binding agents that are protected by blocking agents. Certain RAM provided contain a plurality of protected regions of the support that contain unbound ligand binding agents or enzymes that are retained in the protected regions by a capping agent. Methods of making the RAM of the invention and associated kits are also provided.
