    Abstract: A method for screening host cells expressing a target protein is provided. The method includes the following steps: providing an expression vector, the expression vector including a promoter, a gene encoding a target protein and an FTH1 gene; transfecting the host cells with the expression vector; culturing the host cells in a medium; and adding iron ions to the medium, and screening the surviving host cells to obtain the host cells expressing the target protein. An expression vector and a method for establishing a cell line stably expressing an exogenous recombinant gene are also provided.
