Method of producing a plurality of isolated antibodies to a plurality of cognate antigens

摘要

The present invention relates to a method for producing high affinity antibodies that are antigen-specific. The method involves binding a plurality of antibody-producing B-cells from a mammal to a plurality of cognate antigens; sorting the bound antibody-producing B-cell and cognate antigen; amplifying nucleic acid sequences encoding each antibody, or fragment thereof, from the B-cells; and expressing the each antibody in a protein expression system. Antibodies produced in this manner are useful in diagnostic and therapeutic applications.

主权项

1. A method for producing a plurality of isolated antibodies for profiling antigen expression comprising
(a) binding, in vitro, an isolated plurality of antibody-producing B-cells to an isolated plurality of cognate antigens from a mammal; (b) isolating each cognate antigen-bound antibody-producing B-cell; (c) amplifying each nucleic acid sequence encoding each antibody, or fragment thereof, from each B-cell; (d) introducing each amplified nucleic acid sequence encoding each antibody, or fragment thereof, into an expression system; (e) expressing and purifying each antibody, or fragment thereof; and (f) preparing an array consisting of each purified antibody, or fragment thereof, from step (e) on a substrate for profiling antigen expression.
