In vivo plasmid delivery efficacy. A Fluorescence microscopy examination of splenocytes and liver cells harvested on the 6^th day post ST treatment. BF, bright field; GFP, green fluorescent protein; composite, merged composite image. B FACS-based quantification of plasmid delivery in splenocytes harvested on the 3^rd, 6^th, or 7^th day post ST treatment. The maximum expression of plasmids was observed on the 6^th day post-treatment. An average of three trials was performed, and representative scatter plots are shown.
