  • DNA sequence-based HLA class I typing method
    Patent number: 5593830
    Abstract: The present invention provides a process for determining genotypes in highly polymorphic systems by polymerase chain reaction amplification of cDNA or genomic DNA and direct sequencing polymerase chain reaction products using oligonucleotide primers. More specifically, Class I HLA genotypes can be unambiguously determined in any subject in 16-24 hours by direct sequencing of HLA-A, HLA-B, and HLA-C transcripts enzymatically amplified and sequenced using a limited number of selected oligonucleotide.

  • Molecular farming
    Patent number: 5550038
    Abstract: Novel constructs are provided for expression of physiologically active mammalian proteins in plant cells, either in culture or under cultivation. The constructs provide a promoter functional in a plant host, a structural gene coding for mammalian protein and a terminator functional in a plant host. The construct is introduced into a plant cell to become integrated into the plant genome for expression in the plant cells or plants. The plant cells may be harvested and the mammalian protein isolated in physiologically active form.
