  • Patent number: 6593463
    Abstract: The invention provides modified recombinant nucleic acid sequences (preferably DNA) and methods for increasing the mRNA levels and protein expression of malarial surface protein MSP-1 which is known to be difficult to express in cell culture systems, mammalian cell culture systems, or in transgenic animals. The preferred protein candidates for expression using the recombinant techniques of the invention are MSP-1 proteins expressed from DNA coding sequences comprising reduced overall AT content or AT rich regions and/or mRNA instability motifs and/or rare codons relative to the native MSP-1 gene.

  • Patent number: 6580017
    Abstract: The invention features methods of producing a mammal, e.g., a cloned or transgenic mammal. The method includes maintaining a reconstructed embryo in culture until the embryo is in the 2 to 8 cell stage of embryogenesis, transferring the embryo at the 2 to 8 cell stage into a recipient mammal, and allowing the embryo to develop into a mammal.

  • Publication number: 20030096974
    Abstract: This invention relates to transgenically produced human Antithrombin III (tgATIII). The human ATIII produced by the transgenic process of the present invention has a monosaccharide composition which comprises N-acetylgalactosamine (GalNAc) along with fucose, N-acetylglucosamine, galactose, mannose, and N-acetylneuraminic acid/N-glycolyneuraminic acid. The monosaccharide composition differs with that of plasma derived ATIII (phATIII). It has been found that tgATIII has an increased clearance rate when compared to phATIII.

  • Patent number: 6528699
    Abstract: The invention provides a method of making and secreting a non-secreted protein. The method includes expressing the protein from a nucleic acid construct which includes: (a) a mammary epithelial specific promoter; (b) a milk protein specific signal sequence which can direct the secretion of a protein; (c) optionally, a sequence which encodes a sufficient portion of the amino terminal coding region of a secreted protein to allow secretion in the milk of a transgenic mammal, of the non-secreted protein; and (d) a sequence which encodes a non-secreted protein, wherein elements (a), (b), optionally (c), and (d) are preferably operatively linked in the order recited. Both glutamic acid decarboxylase (GAD) and myelin basic protein (MBP), which are cytoplasmic proteins, have been produced by the methods of the present invention. The invention also provides methods for treating diabetes and multiple sclerosis using proteins produced by the methods of the present invention.

  • Patent number: 6268487
    Abstract: A method of separating a soluble milk component from milk is disclosed. The method involves the use of tangential flow filtration across a membrane to form a retentate and a permeate, combining the permeate with the original milk sample, and repeating this procedure until the milk has been sufficiently purified. Preferably, the milk is combined with a chelating agent, such as EDTA, to improve the purification efficiency. This procedure is advantageously employed with milk from transgenic animals which have been genetically altered to express exogenous proteins, such as therapeutic proteins, in their milk.

  • Patent number: 5756687
    Abstract: Methods of isolating components of interest from a milk sample are described. The methods include a step wherein the solubility of at least a portion of the total milk protein is stabilized in such a manner as to allow isolation of the component of interest without significant loss in yield.
