Abstract

A combinatorial immune library of human single-chain antibodies (scAbs) was constructed using the genes coding for the variable domains of the heavy and light chains of human immunoglobulins. The genes were cloned from lymphocytes of four subjects vaccinated with the vaccinia virus (VACV). The library included 3 · 107 independent clones. After enrichment with clones producing scAbs against a recombinant analog of the variola virus envelope protein prA30L, the library was used to select a panel of scAbs binding both prA30L and VACV. All scAbs selected were tested for virus-neutralizing activity, and two scAbs proved to suppress VACV plaque formation in monolayers of Vero E6 cells. The specificity of antigen binding was verified by ELISA and Western blotting. The amino acid sequences of the virus-neutralizing scAbs were determined by sequencing their genes.
