To assess the efficacy of β2m promoter in dendritic cells, we transduced murine Bone marrow-derived dendritic cells with an integrative lentiviral vector coding for the reporter green fluorescent protein (GFP) at a multiplicity of infection (MOI) of 10, under the regulation of CMV (LV-CMV-GFP) or β2m (LV-β2m-GFP) promoter. The gene discussed is B2M; the disease is infection.
