  • Publication number: 20020099194
    Abstract: The present invention provides a nucleic acid molecule comprising: (a) a region of DNA which is homologous to a region of an endogenous gene present in a genome of a cell of interest; (b) a first nucleic acid encoding an encephalomyocarditis internal ribosome entry site (EMCV IRES); (c) a second nucleic acid encoding a selectable marker which can be excised from the nucleic acid molecule if the nucleic acid molecule has been integrated into the genome of the cell of interest; and (d) a third nucleic acid encoding a gene of interest. The cell may be an animal cell, a yeast cell or a plant cell. The invention also provides for transgenic non-human animals which are created using the above described construct. The invention also provides methods for making such transgenic animals.

  • Patent number: 5830662
    Abstract: This invention provides a method to normalize a directional cDNA library constructed in a vector that allows propagation in single-stranded circle form comprising: (a) propagating the directional cDNA library in single-stranded circles; (b) generating fragments complementary to the 3' noncoding sequence of the single-stranded circles in the library to produce partial duplexes; (c) purifying the partial duplexes; (d) melting and reassociating the purified partial duplexes to appropriate Cot; and (e) purifying the unassociated single-stranded circles, thereby generating a normalized cDNA library. This invention also provides normalized cDNA libraries generated by the above-described method and uses of the generated libraries.

  • Patent number: 4565785
    Abstract: A plasmid or phage gene for a periplasmic or extracellular bacterial protein is cleaved, a double-stranded DNA sequence coding for a selected protein or portion thereof from a eukaryotic cell such as insulin is inserted in that cleaved gene by recombinant DNA techniques and used to transform a bacterium, and the excreted selected protein is collected.
