Abstract: Ribosome display is a powerful cell-free technology to select a desired antibody together with its encoding mRNA. In this study, a human single-chain variable fragment (scFv) library was generated from the peripheral blood lymphocyte RNA of 10 ovarian cancer patients and then panned against bead-conjugated human PlGF, a protein that may contribute to the growth and metastasis of ovarian cancer. A selected scFv antibody was evaluated by Western blot and its affinity constant to the PlGF was determined by noncompetitive enzyme immunoassay. This study highlights the ribosomal display technology for the selection of human antibody from patient-derived gene pools.
