Patents by Inventor Diana Jespersen

Diana Jespersen has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method of screening a population of cells
    Patent number: 7556928
    Abstract: The invention provides methods of analyzing a secreted protein from a cell encapsulated in a microdrop. The microdrop is formulated with biotinylated matrix molecules at a reduced ratio of biotin to matrix molecules compared with previous formulations. The reduced ratio is advantageous for improving the resolution of detection and allows simultaneous detection of multiple secreted proteins and/or multiple cell surface markers. The invention further provides inter alia methods of isolating IgG isotype antibodies that have switched from IgM isotype.
    Type: Grant
