• A) Mix epithelial cells with heat-killed virus, wait 24 hrs, wash away any virus particles outside the epithelial cells, then add epithelial cells to dendritic cells.
• B) Mix epithelial cells with viral peptides, wait 24 hrs, wash away any viral peptides not bound to the epithelial cells, then add epithelial cells to dendritic cells.
• C) Mix epithelial cells with live virus particles, wait 24 hrs, wash away any virus particles outside the epithelial cells, then add epithelial cells to dendritic cells.
• D) Mix dendritic cells with viral nucleic acids and epithelial cells for 24 hrs.
• E) MIx epithelial cells will viral nucleic acids, wait 24 hrs, wash away any viral nucleic acid remaining outside the epithelial cells, then add epithelial cells to dendritic cells.
