FIELD: medicine. ^ SUBSTANCE: invention can be used for obtaining diagnostic and/or therapeutic agents, in particular antibodies, which specifically interact with proteins of cell surface of target cells. Claimed is method of screening phage display library and including it method of isolation of library element, which is specific partner of binding of target cell surface protein, and method of isolation of unknown cell surface protein, specifically interacting with library element. Method of screening phage display library according to invention includes contact of said library with cells of interest with further separation of cells, which bound with one or several elements of expression library, from non-bound elements by separation through organic phase, and differs by introduction of additional stage, which consists in carrying out before said separation of at least one stage of material washing, and ensures essential increase of method efficiency. ^ EFFECT: higher efficiency. ^ 30 cl, 7 dwg, 6 ex |
