Abstract

The display of proteins on the surface of phage offers a powerful means of selecting for rare genes encoding proteins with binding activities. Recently we found that antibody heavy and light chain variable (V) domains fused as a single polypeptide chain to a minor coat protein of filamentous phage fd, could be enriched by successive rounds of phage growth and panning with antigen. This allows the selection of antigen-binding domains directly from diverse libraries of V-genes. Now we show that heterodimeric Fab fragments can be assembled on the surface of the phage by linking one chain to the phage coat protein, and secreting the other into the bacterial periplasm. Furthermore by introducing an amber mutation between the antibody chain and the coat protein, we can either display the antibody on phage using supE strains of bacteria, or produce soluble Fab fragment using non-suppressor strains. The use of Fab fragments may offer advantages over single chain Fv fragments for construction of combinatorial libraries.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
