  • Secretions of proteins by encapsulated cells
    Patent number: 6806058
    Abstract: The invention provides methods of analzying 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
