  • Publication number: 20060191025
    Abstract: The present invention provides for the production of homozygous primary cells that carry a specific transgenic integration of interest on both chromosomes by bypassing breeding. These cell lines can they be used for the accelerated production of homozygous transgenic animals by somatic cell nuclear transfer. The invention is thus useful in the production of transgenic ungulate animals capable of producing desired biopharmaceuticals in their milk at higher yield than a comparable heterzygote. By combining the selection techniques of the current invention with somatic cell nuclear transfer it can be applied to large animals, where there is a strong need to shorten the time to homozygosity.

  • Publication number: 20060179500
    Abstract: The invention features methods of making transgenic animals, and transgenic animals made by such methods. The method includes introducing into a cell, a nucleic acid construct comprising a nucleic acid sequence encoding a heterologous polypeptide under the control of a mammary epithelial cell promoter, an insulator positioned 5? from the promoter, an insulator positioned 3? from the nucleic acid sequence encoding the polypeptide, and a prokaryotic sequence, wherein the sequence between the insulator 5? from the promoter and the insulator 3? from the nucleic acid encoding the polypeptide is substantially free of prokaryotic sequence; and allowing a transgenic mammal to develop from the cell, to thereby provide a transgenic mammal.

  • Publication number: 20060123500
    Abstract: The present invention provides for the production of transgenic animals through pre-screening methods designed to improve the efficiency of nuclear transfer and consequentially the production characteristics of transgenic mammals relative to proteins of interest. The invention is thus useful in the production of transgenic ungulate animals capable of producing desired biopharmaceuticals in their milk at higher yield than a comparable heterzygote or producing animals with better physiological attributes.

  • Publication number: 20050193431
    Abstract: The invention features a purified embryonic or fetal caprine somatic cell. The somatic cell can be in a preparation of embryonic or fetal caprine somatic cells. In addition, the cell can be used to derive an embryonic or fetal caprine somatic cell line.

  • Publication number: 20040226052
    Abstract: The invention provides systems and methods for the production and purification of target molecules present in biological systems. The systems and methods according to the invention utilize transgenic expression of multivalent binding polypeptides, as affinity media, to purify such target molecules. The transgenic multivalent binding polypeptides bind both the target molecules, e.g., a bindable epitope of a target molecule, and a matrix.

  • Publication number: 20040148648
    Abstract: The present invention provides method to improve the efficiency of both serial nuclear transfer and the consequent production of transgenic cells and/or animals. This new method, through the use of at least a second round of nuclear transfer, will enable donor cells to correct their reprogramming more efficiently generating larger numbers of useful transgenic embryos. Because the reprogramming of the embryos generated is enhanced the current invention will allow for the production of healthier transgenic animals.
