Figure 2. The SAα2–6Gal expression of primary CTE cells.

The mucin (A), K14 (B) and β-tubulin (C and D) were the markers for goblet cells, basal cells and ciliated cells, respectively. The cellular distribution of SAα2–6Gal was shown by the double-staining of biotin-labeled SNA (Vector Laboratories, 1∶500) (A–C) and SNA-1 (EY laboratories, 1∶500) (D). Scale bar, 50 µm.
