Phage libraries for generation of clinically useful antibodies

Abstract

Insertion of antibody genes into filamentous bacteriophage makes it possible to generate and screen libraries of 107 or more antibodies. Each phage expresses an antibody on its surface and contains the corresponding antibody gene. Genes that encode antibodies with desired characteristics are readily selected and their antibodies expressed as soluble proteins in Escherichia coli. We used this system to produce an antibody to carcinoembryonic antigen with higher affinity and better tumour specificity than antibodies currently in use.

    It was shown that repeated injections of non-human antibodies led to a strong immune response that significantly limited or undermined their therapeutic efficacy [2,4,6]. Hence, full human mAbs have since emerged as a result of several approaches, including the phage display method and transgenic mouse system with an entire human antibody repertoire [7–12]. However, transgenic mouse system is lengthy and costly.

    Results are shown as mean value ± S.D. ScDb-IgBD and scFv-IgBD fusion proteins were generated by fusing IgBDs from SpA, SpG, or PpL to the C terminus of a bispecific single-chain diabody directed against CEA and CD3 (scDb CEACD3) or a single-chain Fv directed against CEA (scFv CEA) (17) (Fig. 2a). From SpA we used domain B (18), domain D (9), and a modified version of domain E, which was described to exhibit increased thermal stability (19).

    MFE-23 is an antibody single-chain variable fragment (scFv) directed against CEA. Originally identified by phage library selection, this scFv was later humanized by resurfacing and engineered in yeast for greater stability and solubility (shMFE) as well as affinity (sm3E) (31–33). Both of these engineered molecules are well expressed in yeast and have Kd values of ∼7 nm and ∼30 pm, respectively.
