    • A method of broadening epitopic coverage of an antigen of interest, wherein a first sample of the antigen of interest is contacted with a first plurality of host cells collectively expressing a first library of antibodies. Host cells expressing antibodies that bind to the antigen are then collected from among the first plurality of host cells, and a composition is prepared comprising a polyclonal mixture of antibodies expressed by these host cells. A second sample of the antigen of interest is then contacted with an aliquot of the prepared composition and a second plurality of host cells collectively expressing a second library of antibodies. Host cells expressing antibodies that bind to the second sample of the antigen are then collected from among the second plurality of host cells.
    • 扩大感兴趣抗原的表位覆盖的方法,其中感兴趣抗原的第一样品与共同表达第一抗体库的第一多个宿主细胞接触。 然后从第一批多个宿主细胞中收集表达与抗原结合的抗体的宿主细胞,并制备包含由这些宿主细胞表达的抗体的多克隆混合物的组合物。 然后使目的抗原的第二样品与制备的组合物的等分试样和共同表达第二抗体库的第二多个宿主细胞接触。 然后从第二多个宿主细胞中收集表达与第二抗原样品结合的抗体的宿主细胞。
