Prenatal lethality in a transgenic mouse line is the result of a chromosomal translocation.

We have produced a line of transgenic mice that is characterized by prenatal lethality. These mice bear a chimeric plasmid containing the long terminal repeat of the Rous sarcoma virus linked to the coding region of the chloramphenicol acetyltransferase gene (pRSV-CAT). Mice heterozygous for the pRSV-CAT integration site are semisterile, producing litters… CONTINUE READING
