Fig.(1) Results of Immunocytochemistry. Differential binding of MAL II Lectin-FITC to transfected cell lines. In panels A (BPV) and C (WT) there is notable binding of MAL II Lectin-FITC, which binds selectively to sialic acid at the α2, 3 position on cell borders. Panel B (ΔF508) has a qualitative decrease in binding to this lectin. Bar =10um.
