Peptide production

Abstract

Abstract A method of producing a substance comprising a peptide, involves incorporating a DNA sequence coding for the peptide into a gene of a mammal (such as a sheep) coding for a milk whey protein in such a way that the DNA sequence is expressed in the mammary gland of the adult female mammal. The substance may be an (optionally modified) protein such as a blood coagulation factor. The DNA sequence is preferably inserted into the first exon of a gene coding for a whey protein such as beta-lactoglobulin. The substance will generally be recovered from milk of the female mammal, but may (for example if it is an enzyme) be used in situ.
