Summary for Patent: 5,650,503
Title: Genetic construct of which protein coding DNA comprises introns and is designed for protein production in transgenic animals
Abstract:Proteinaceous products can be produced by transgenic animals having genetic constructs integrated into their genome. The construct comprises a 5\'-flanking sequence from a mammalian milk protein gene (such as beta-lactoglobulin) and DNA coding for a heterologous protein other than the milk protein (for example a serin protease such as alpha.sub.1 -antitrypsin or a blood factor such as Factor VIII or IX). The protein-coding DNA comprises at least one, but not all, of the introns naturally occurring in a gene coding for the heterologous protein. The 5\'-flanking sequence is sufficient to drive expression of the heterologous protein.
