Western blotting analysis of survivin protein in oral cancer cell lines. Lysates from oral cancer cell lines or normal oral mucosal tissue were resolved by 10% SDS-PAGE and transferred to PVDF membranes. The membranes were then incubated with mouse anti-human survivin monoclonal antibody (upper panel) or mouse anti-β-actin monoclonal antibody AC-15 (lower panel).
