SMOX and infection: To investigate the involvement of lipid rafts in the SHIP-1 model, we transfected AM cells with SHIP-1 siRNA (knocking down confirmed by western blotting) and then infected the cells with GFP–PAO1 at 20:1 of multiplicity of infection (MOI) to track lipid rafts using CTB conjugated with Alexa FluorTM 594.
