Copy Number Estimate in Uterine Contents of Transgenic Animals. Values represent the vector copy number per 0.2 μg of DNA for placenta, placentomal and interplacentomal tissues. The mean copy number of internal organs is also provided for comparison. In general the placenta and internal organs are similar in copy number. The placentomal and interplacentomal tissues are generally lower in copy number consistent with the fetal and maternal origins of these structures.
