摘要:
The invention relates to transgenic avians which produce antibodies in the egg white by introducing a nucleic acid sequence into the genome of an avian embryo wherein the nucleic acid sequence comprises a nucleotide sequence encoding an antibody and to the antibodies and to methods related thereto.
摘要:
The invention includes methods of making transgenic avians by introducing a nucleic acid sequence into the genome of an avian embryo wherein the nucleic acid sequence comprises a nucleotide sequence encoding a heterologous protein, developing the avian embryo to hatch, developing the hatched chick to sexual maturity and obtaining offspring from the sexually mature hatched chick which produce egg white containing the heterologous protein.

The invention includes methods of enucleating avian eggs comprising visualizing internal structure of an avian egg utilizing TPLSM and ablating the nucleus of the egg by near-infrared light.
摘要:
This invention provides methods for the stable introduction of heterologous coding sequences into the genome of a bird and expressing the coding sequences to produce desired proteins or to alter the phenotype of the bird. The present invention provides preferred methods for introducing a transgene into the cytoplasm of avian embryonic cells by cytoplasmic microinjection. The embryo then develops into a transgenic adult capable of expressing a heterologous protein and/or capable of generating a line of transgenic birds through breeding. Synthetic vectors and gene promoters useful in the methods are also provided by the present invention, as are transgenic birds that express heterologous protein and avian eggs containing heterologous protein.
