In particular, the method involves expressing a library of antibodies or antibody mimetics in a population of mammalian cells, wherein each cell in the population of cells displays the target polypeptide on the outer surface of N the cell, and identifying or isolating cells within the population of cells to which antibodies or antibody mimetics are bound.
