EXPRESSION OF A HETEROLOGOUS POLYPEPTIDE IN MAMMARY TISSUE OF TRANSGENIC NON-HUMAN MAMMALS USING ALONG WHEY ACDIC PROTEIN PROMOTER
Date of this Version
Patent Number: 5,831,141
Heterologous polypeptides are produced in the milk of transgenic non-human mammals by the expression of a Stably integrated DNA sequence containing the long whey acidic protein promoter operably linked to a DNA sequence encoding a heterologous polypeptide and a signal Sequence. The transgenic non-human mammals of the present invention are produced by introducing this DNA sequence Such that the DNA sequence is stably integrated into the DNA of germ line cells of the mature mammal and inherited in normal Mendelian fashion. A representative heterologous polypeptide is protein C.
