Intracellular expression of Bcl-2 family proteins in HUVECs. After HUVECs were stimulated with or without TNF-α (100 ng/ml) for 6 h, the cells were incubated in the presence and absence of IVIG (20 mg/ml) for 12 h. The cell lysates were analysed by SDS-PAGE and immunoblotting. Pre indicates the HUVECs before TNF-α stimulation.
