PCT No. PCT/GB96/00468 Sec. 371 Date Nov. 12, 1997 Sec. 102(e) Date Nov. 12, 1997 PCT Filed Mar. 1, 1996 PCT Pub. No. WO96/27612 PCT Pub. Date Sep. 12, 1996Associative portions of antibody light and heavy chains, especially Fv fragments, are expressed in a transformed organism as a single peptide chain connected by a linking peptide. This is cleaved, possibly while peptide synthesis is incomplete, by an enzyme of the transformed organism which is expressing the single peptide. This ensures production of both chains in equal amounts, but produces them as separate chains which are free to associate and fold. |
