title: Different activities of viral enhancer elements before and after stable integration of transfected DNAs.
abstract: Analysis of the RNA and DNA levels of a selectable gene linked to a murine retroviral enhancer demonstrated a correlation between RNA levels and tissue-specific enhancer activity during transient expression in T cells but not in stably transformed cell lines.
