  • Transcriptional regulatory sequence of carcinoembryonic antigen for expression targeting
    Patent number: 6194211
    Abstract: The transcriptional regulatory sequence (TRS) of Carcinoembryonic Antigen (CEA) and molecular chimeras comprising the CEA TRS and DNA encoding a heterologous enzyme are described. Such molecular chimeras are capable of targeting the expression of the heterologous enzyme to CEA-positive cells. The heterologous enzyme may be cytosine deaminase.
