ABSTRACT:
In the production of proteins of biological interest by means of a stress inducible gene expression unit/eukaryotic host cell system, the transformed cell lines are multiplicated by tumour growing in immunodefficient warm-blooded animals, after which the multiplicated cells are cultured in vitro and subjected to stress, whereby expression occurs in high yield. In vivo multiplication rates of 10.sup.5 -10.sup.6 the innoculated quantity/2 weeks are reported without any loss of the latent inducible expression capacity.
