Abstract

Abstract This invention relates to processes and intermediates for improving the level of production of a desired polypeptide in a recombinant host whose genome has integrated into it an island of expression comprising in the 5' to 3' direction, a 5' flanking region, the heterologous polypeptide encoding sequence and a 3' flanking region. The island of expression of this invention permits the expression of the integrated heterologous DNA sequence to be substantially dependent on its copy number and to be substantially independent of its position of integration in the host genome.
