    摘要: A microscope system, kit and method are described for observation of cellular activity in real time. The system is used to monitor cell transfection using a polynucleotide noncovalently attached to a carrier, The carrier labeled with a dye or fluorescent agent so that transport of complex can be monitored in real time. The polynucleotide includes both a gene of interest and a reporter gene. The reporter gene indicates successful expression of the gene of interest.
