The process comprises depositing a heterogeneous cell mixture one or plural surfaces with predefined structures causing cells with corresponding target structures to become bound to such surface(s), removing any non-binding cells of said cell mixture from said surface, identifying the cell-specific target structures responsible for the binding of the cells to said surface(s), selecting and enriching cells with identical cell-specific target structures on said surface(s), and biochemically characterizing the target structures.Type: GrantFiled: March 14, 2001Date of Patent: December 13, 2005Inventor: Walter Schubert

Patent number: 6924115Abstract: This invention relates to a process for identifying cell-specific target structures. The process comprises automatically depositing a reagent solution that includes at least one marker molecule on an object which contains cells and/or cell membranes originating from a cell or tissue sample, allowing the reagent solution to react and automatically detecting at least one marker pattern of the object labeled with the reagent solution, removing said reagent solution, combining detected marker patterns, repeating the process with at least one further object, determining at least one difference in the objects, identifying at least one reagent solution causing the at least one difference, selecting molecules or molecular complexes from a homogenate of cells and/or cell membranes, and biochemically characterizing these molecules or molecular complexes.Type: GrantFiled: March 14, 2001Date of Patent: August 2, 2005Inventor: Walter Schubert

Patent number: RE45196Abstract: The present invention provides compositions comprising conjugate molecules that are structurally stable at a temperature of between about 2 degrees C. and 8 degrees C. In some examples, a conjugate molecule comprises an antigen, such as an allergen. In some examples, a conjugate molecule comprises the Ragweed antigen Amb a 1. The present invention provides methods for making and using such compositions. Provided herein are methods for modulating an immune response in an individual comprising administration of a composition comprising a structurally stable conjugate molecule as described herein.Type: GrantFiled: May 18, 2012Date of Patent: October 14, 2014Assignee: Dynavax Technologies CorporationInventors: Stephen F. Tuck, Roberto Rodriguez
