ABSTRACT:
The present invention relates to disulfide-stabilized recombinant polypeptide molecules which have the binding ability and specificity for another peptide, such as the variable region of an antibody molecule. Methods of producing these molecules and nucleic acid sequences encoding these molecules are also described. In particular, the invention discloses Fv antibody fragments stabilized by a disulfide bond connecting the V.sub.H and V.sub.L regions of the Fv fragment. The .alpha. and .beta. chains of T cell receptors may be similarly stabilized by means described in the invention.
