Popis: Single-chain antibodies consist of the variable, antigen-binding domains of antibodies joined to a continuous polypeptide by genetically engineered peptide linkers. We have used the flexible interdomain linker region of a fungal cellulase to link together the variable domains of an anti-2-phenyloxazolone IgGl and show here that the resulting single-chain antibody is efficiently secreted and released to the culture medium of Escherichia coli. The yield of affinity-purified single-chain antibody is 1 -2 mg/1 of culture medium and its affinity and stability are comparable to those of the corresponding native IgG.
