    • Nucleotide sequences encoding proteins of interest are isolated from DNA libraries using bacteriophage to link the protein to the sequence which encodes it. DNA libraries are prepared from cells encoding the protein of interest and inserted into or adjacent to a coat protein of a bacteriophage vector, or into a sequence encoding a protein which may be linked by means of a ligand to a phage coat protein. By employing affinity purification techniques the phage particles containing sequences encoding the desired protein may be selected and the desired nucleotide sequences obtained therefrom. Thus, for example, novel proteins such as monoclonal antibodies may be produced and conventional hybridoma technology avoided.
    • 使用噬菌体从DNA文库中分离编码感兴趣的蛋白质的核苷酸序列,以将蛋白质与编码它的序列连接。 从编码感兴趣的蛋白质的细胞和插入到噬菌体载体的外壳蛋白中或邻近的蛋白质制备DNA文库,或者将其编码为可通过配体与噬菌体外壳蛋白连接的蛋白质的序列。 通过使用亲和纯化技术,可以选择含有编码所需蛋白质的序列的噬菌体颗粒和从其获得的所需核苷酸序列。 因此,例如,可以产生新的蛋白质,例如单克隆抗体,并避免常规的杂交瘤技术。
