  • Hybrid plasmid with marker
    Patent number: 4670399
    Abstract: Recombinant plasmids adopted for transformation of prokaryotic and eukaryotic hosts having an insertion site for at least one DNA fragment are provided. In a preferred embodiment, nucleotide sequences coding for methotrexate-resistant dehydrofolate reductase and a nucleotide sequence, a portion thereof coding for a promoter, are ligated into the insertion site.
