Transgenic Mice Expressing Human Lactoferrin Gene in Milk

According to Mendel's principles,the transgenic mice with human lactoferrin(hLTF) were bred.Through hybridization,we obtained three homozygous(P1♀,Q1♀1♂) and six double-heterozygous(3♀3♂) mice.All of the milk of female transgenic mice was collected,and hLTF protein was measured by ELISA method.The results showed that hLTF expression in the milk of double-heterozygous transgenic mice was much highe…
