Figure 4From: Acinetobacter baumannii invades epithelial cells and outer membrane protein A mediates interactions with epithelial cellsCell surface binding of rAbOmpA. The grey shaded region represents the control fluorescent level seen in the cells treated with polyclonal anti-rabbit AbOmpA antibody and Alexa Fluor ® 488-conjugated secondary antibody without the addition of rAbOmpA. The solid line represents the fluorescent level seen in the cells treated with 6 μg/ml of rAbOmpA.Back to article page
