EXPRESSION CASSETTE FOR USE IN ANIMALS COMPRISING PROMOTER AND 3' NON-CODING SEQUENCE OR PORTION THEREOF OF EXON 5 OF GROWTH HORMONE GENE, AND TRANSGENIC ANIMALS

摘要

The present invention provides a genetic expression cassette for use in obtaining expression of a cDNA sequence in animal cells. The expression cassette comprises an inducible promoter and the 3' non-coding sequence of exon 5 of the growth hormone gene or a portion thereof. The cDNA sequence is inserted between the inducible promoter and the exon 5 of the growth hormone genes.
