The green fluorescent protein (GFP) gene was expressed on a plasmid in B. henselae, and GFP-expressing bacteria were visualized by fluorescence microscopy. HEp-2 cells infected with GFP-expressing bacteria were separated from uninfected cells with a fluorescence activated cell sorter. Promoter fusions of B. henselae chromosomal DNA to gfp were examined by flow cytometry, and a B. henselae groEL promoter fusion which induced expression at 37 degreesC was isolated.
绿色荧光蛋白(GFP)基因在汉赛巴尔通体的质粒上表达,通过荧光显微镜观察到表达GFP的细菌。用荧光激活细胞分选仪将感染了表达GFP细菌的HEp-2细胞与未感染的细胞分离。通过流式细胞术检测汉赛巴尔通体染色体DNA与gfp的启动子融合情况,并分离出在37℃诱导表达的汉赛巴尔通体groEL启动子融合体。
