Producing complex recombinant proteins in the milk of transgenic animals offers several advantages: large amounts of proteins can be obtained, and in most cases, these proteins are properly folded, assembled, cleaved, and glycosylated. The level of expression of foreign genes in the mammalian gland cannot be predicted in all cases, and appropriate vectors must be used. The main elements of these vectors are as follows: A well-characterized specific promoter, the coding region of the gene of interest, preferably with a homologous or heterologous intron, to improve transcription efficiency, and an insulator or boundary element to counteract the chromosomal position effects at the integration site. Once high expression levels are achieved, and the recombinant protein is purified, an essential step in the analysis of the final product is determining its degree of glycosylation. This is an important readout because it can affect among other parameters the stability and immunogenicity of the recombinant protein.
