摘要:
The invention is drawn to a composition comprising an isolated mixture of cytotoxic anti-CD20 antibody molecules produced in a transgenic avian. The antibody molecules have a heavy chain and a light chain whose amino acid sequences set forth in SEQ ID NOs: 4 and 5 and exhibit an increased level of cytotoxicity as compared to anti-CD20 antibody molecules produced in CHO cells.

摘要:
This invention provides vectors and methods for the stable introduction of exogenous nucleic acid sequences into the genome of a bird and for expressing said exogenous sequences to alter the phenotype of the bird or to produce desired proteins. In particular, transgenic chickens are produced which express exogenous sequences in their oviducts. Eggs which contain exogenous proteins are also produced.
摘要:
The present invention presents the isolation, characterization and synthesis of oligosaccharides of Bacillus anthracis. Also presented are antibodies that bind to such saccharide moieties and various methods of use for such saccharide moieties and antibodies.
摘要:
This invention provides vectors and methods for the stable introduction of exogenous nucleic acid sequences into the genome of avians in order to express the exogenous sequences to alter the phenotype of the avians or to produce desired proteins. In particular, transgenic avians are produced which express exogenous sequences in their oviducts and which deposit exogenous proteins into their eggs. Avian eggs that contain exogenous proteins are encompassed by this invention. The instant invention further provides novel forms of interferon and erythropoietin which are efficiently expressed in the oviduct of transgenic avians and deposited into avian eggs.

Methods of producing protein using a recombinant ovomucoid gene expression controlling region operably linked to one or more useful amino acid coding sequences.
摘要:
The present invention provides novel isolated nucleic acids that comprise an avian nucleic acid sequence comprising a ovomucoid gene expression control region. The ovomucoid promoter region of the present invention will allow expression of an operably linked heterologous nucleic acid insert in a transfected avian cell such as, for example, an oviduct cell. The isolated avian ovomucoid of the present invention may be operably linked with a selected nucleic acid insert, wherein the nucleic acid insert encodes a polypeptide desired to be expressed in a transfected cell. The recombinant DNA of the present invention may further comprise a polyadenylation signal sequence. The present invention further includes expression vectors comprising an isolated avian ovomucoid gene expression control region of the present invention, and transfected cells and transgenic avians comprising the expression vectors.
