Figure 2From: Gene silencing of β-galactosamide α-2,6-sialyltransferase 1 inhibits human influenza virus infection of airway epithelial cells Treatment with ST6GAL1 siRNAs inhibited SAα2,6Gal expression on cell surfaces. A549 cells were treated with ST6GAL1 or control siRNAs. SAα2,6Gal was stained with SNA-FITC (green) and cell nuclei were counterstained with DAPI (blue). (A) Untreated cells. (B) Control siRNAs. (C) ST6GAL1 siRNAs.Back to article page
