To confirm that ST6Gal-I knockdown corresponded with a decrease in α2–6 sialic acid on the cell surface, staining was performed with SNA lectin, which binds to α2–6 sialic acid. Briefly, cells were incubated with FITC-conjugated SNA (Vector, B-1305) at a 1:400 dilution for 20 minutes at 4°C. SNA staining was then quantified via flow cytometry using an LSR-II (BD Bioscience).
