Disclosed is a method of screening binding molecules, including Monoclonal Antibodies, using an optical fiber array device. Target cells are coated onto a population of microbeads, wherein each microbead is coated with several cells of the same cellular type and has an assay and an assay reporter associated with it. Each of the cell-coated microbeads is positioned in a particular well formed in one end of a particular fiber in an array of optical fibers. The microbeads are contacted with binding molecules, and the results of an assay associated with a microbead are reported to the distal end of the array of fibers.

La présente invention concerne un procédé pour cribler des molécules de liaison, y compris des anticorps monoclonaux, au moyen d'un dispositif à réseau de fibres optiques. Des cellules cibles sont appliquées sur une population de microbilles, chaque microbille étant revêtue avec plusieurs cellules du même type cellulaire et étant associée à un dosage et à un reporteur de dosage. Chacune des microbilles revêtue par des cellules est placée dans un puits particulier, formé à une extrémité d'une fibre particulière dans un réseau de fibres optiques. Les microbilles sont mises en contact avec des molécules de liaison et les résultats d'un dosage associé à une microbille sont reportés à l'extrémité distale du réseau de fibres.
