Expression of full length igg and secretion into the culture medium of prokaryotic cells

Abstract

A method for the production of an immunoglobulin or a functional fragment thereof in a prokaryotic host cell comprises transforming the host cell with (a) a first nucleic acid molecule comprising a nucleic acid sequence encoding a VL and a CL region and (b) a second nucleic acid molecule comprising a nucleic acid sequence encoding a VH, a CH1, a CH2 and at least a portion of a CH3 region, The host cell is within culture medium. The host cell is cultured under conditions so as to allow the host cell (a) to express (1) the VL and a CL region and (2) the VH, the CH1, the CH2 and the portion of the CH3 region, and (b) to secrete (a)(1) and (a)(2) to the periplasm of the host cell and thereafter to the culture medium of the host cell. Characteristically, (a)(1) and (a)(2) interact to form the immunoglobulin or functional fragment thereof.
