Production of protein of interest in the milk of transgenic mammal.

摘要

The present invention relates to a process for the preparation of a heterologous protein of interest in the mature form or in the fused form from the milk of mammalian female, a process in which: - the said female is bred and, - the milk is recovered from which the said protein is recovered and separated if necessary, characterised in that the said female is a transgenic animal into whose genome a sequence encoding the said protein of interest has been integrated under the control of at least one sequence which is among the elements for the expression of rabbit WAP protein and which is present in the fragment which is at least 3 Kb in length from the 3% end of the complete WAP promoter. It also relates to the milk product obtained and to an eukaryotic cell which has integrated the sequences described.
