Efficient tissue‐specific expression of bovine α‐lactalbumin in transgenic mice

Abstract
Transgenic mice carrying a 3.2-kb genomic fragment comprising the bovine α-lactalbumin gene transcription unit with 750 bp and 336 bp of 5′ and 3′ flanking regions, respectively, were generated. Tissue-specific expression of the transgene was observed in five out of the six lines analyzed at levels close to the endogenous gene in two of them.
