ABSTRACT:
The invention relates to modified neomycin phosphotransferase genes and their use in a selection method for high-producing recombinant cells. The invention further relates to expression vectors which contain a modified neomycin phosphotransferase gene and a gene of interest functionally linked to a heterologous promoter and a method of preparing heterologous gene products using these expression vectors.
