  ABSTRACT: An IgG1k lambda Fab library was generated on the surface of phage beginning with bone marrow RNA from a healthy 22-year-old human donor. The donor had been immunized to measles in his early childhood but had only a low serum titer to a measles antigen preparation. The resulting library of approximately 10(7) clones was panned against the measles antigen preparation and three positive Fab-producing clones identified by ELISA. One of the Fabs was found to be specific to measles and to bind with high apparent affinity (10(8) M-1). The other two bind with lower affinity and show marked cross-reactivity with a number of other antigens. They possess heavy chains derived, with extensive somatic modification, from the single member gene family VH6. The study indicates that both high-affinity specific antibodies and lower affinity polyreactive antibodies can be derived from the library approach under appropriate conditions.

  ABSTRACT: The combinatorial phage library approach to immunoglobulin repertoire cloning recently made it possible to isolate gene fragments encoding human immunoglobulin G1 Fabs binding with high affinity to specific antigens. Here we describe the construction of genes encoding whole human anti-tetanus toxoid antibodies based on one of these gene fragments and the efficient expression of these constructs by co-transfection of separate heavy and light chain vectors into a Chinese hamster ovary cell line constitutively expressing a viral transactivator protein. This system will be generally useful for the rapid analysis of recombinant antibodies derived from combinatorial libraries.
