TLDR
It is shown that complete antibody V domains can be displayed on the surface of fd bacteriophage, that the phage bind specifically to antigen and that rare phage can be isolated after affinity chromatography.Abstract:
NEW ways of making antibodies have recently been demonstrated using gene technology. Immunoglobulm variable (V) genes are amplified from hybridomas or B cells using the polymerase chain reaction, and cloned into expression vectors. Soluble antibody fragments secreted from bacteria are then screened for binding activities (see ref. 1 for review). Screening of V genes would, however, be revolutionized if they could be expressed on the surface of bacteriophage. Phage carrying V genes that encode binding activities could then be selected directly with antigen. Here we show that complete antibody V domains can be displayed on the surface of fd bacteriophage, that the phage bind specifically to antigen and that rare phage (one in a million) can be isolated after affinity chromatography.read more

TL;DR: In this paper, a member of a specific binding pair (sbp) is identified by expressing DNA encoding a genetically diverse population of such sbp members in recombinant host cells in which the sbps members are displayed in functional form at the surface of a secreted recombinant genetic display package (rgdp) containing DNA encoding the sbp member or a polypeptide component thereof.

Rapid evolution of a protein in vitro by DNA shuffling.
TL;DR: It is reported here that selected mutants had a minimum inhibitory concentration of 640 μg ml-1, a 32,000-fold increase and 64-fold greater than any published TEM-1 derived enzyme.

Filamentous fusion phage: novel expression vectors that display cloned antigens on the virion surface
TL;DR: Foreign DNA fragments can be inserted into filamentous phage gene III to create a fusion protein with the foreign sequence in the middle that is incorporated into the virion, which retains infectivity and displays the foreign amino acids in immunologically accessible form.
