RT Journal Article SR 00 ID 10.1515/bc.1999.036 A1 Bischof, J. A1 Vietor, I. A1 Cotten, M. A1 Huber, L.A. T1 Transient transfection of mammary epithelial cells with a PEI/DNA/adenovirus system JF Biological Chemistry YR 1999 FD 1999-02 VO 380 IS 2 SP 269 OP 273 AB Studies on epithelial cells often require the transient expression of exogenous proteins in polarized epithelial cells. However, the major limitation of this approach has been the difficulty of obtaining transient gene expression in polarized epithelial cell cultures. We report here on the application of a polyethylenimine (PEI)/DNA/adenovirus system for efficient transient gene expression in mammary epithelial cells. Based on luciferase assay and FACScan analysis the PEI/DNA/adenovirus system is shown to be an effective and simple method for transfecting epithelial cells.
