    Immunoglobulin domains owe a crucial fraction of their conformational stability to an invariant central disulfide bridge, the closure of which requires oxidation. Under the reducing conditions prevailing in cell cytoplasm, accumulation of soluble immunoglobulin is prohibited by its inability to acquire and maintain the native conformation. Previously, we have shown that disulfide-free immunoglobulins can be produced in Escherichia coli and purified from cytoplasmic extracts.
