  • Publication number: 20040072283
    Abstract: A simple and highly efficient method for cloning cDNAs from mammalian expression libraries based on transient expression in mammalian host cells has been discovered. Novel expression vectors allowing highly efficient construction of mammalian cDNA libraries are disclosed. The cloning method of the invention which has been used to clone genes for cell surface antigens of human lymphocytes, has general application in gene cloning. Cell surface antigens cloned according to the present invention have been purified, and the nucleotide and amino acid sequences determined. These antigens have diagnostic and therapeutic utility in immune-mediated infections in mammals, including humans.

  • Patent number: 5358857
    Abstract: Fusion proteins are obtained in high yields if a mixed oligonucleotide is constructed which codes for the ballast constituent of the fusion protein. The oligonucleotide mixture is introduced in a vector in such a manner that it is functionally linked to a regulatory region and to the structural gene for the desired protein. Appropriate host cells are transformed with the plasmid population obtained in this manner and the clones producing a high yield of coded fusion protein are selected.
