Figure Lengend Snippet: Immune recognition of glycan structures on PaTu-S and PaTu-T cells. (A) Interaction of immature DCs with PaTu-S and PaTu-T were visualized by fluorescence microscopy. Bar = 100 μm. (B) Binding of immature DCs to PaTu-S and PaTu-T in a cell adhesion assay, in the presence or absence of EGTA. Results are derived from 6 independent experiments using different donors and expressed as average percentage binding ± SEM. (C) Binding of recombinant human galectins Gal-1, Gal-3, and Gal-4 (5 μg/ml) to the PDAC cell lines was measured by flow cytometry. Results are given as average MFI ± SEM of at least 2 independent experiments. (D) Binding of Fc-chimeras of DC-SIGN, MGL, DCIR and Dectin-1 to PaTu-S and PaTu-T cells was measured by flow cytometry. Results are given as average MFI ± SEM of at least 3 independent experiments. * P ≤ 0.05, ** P ≤ 0.01, and *** P ≤ 0.001.
Article Snippet: Mouse anti-human galectin (Gal)-1 , and anti-Tn monoclonal antibodies were kindly provided by Dr. RD Cummings (Boston, USA), goat anti-human Gal-4 was purchased from R&D Systems (Minneapolis, MN) and anti-sialyl Lewis A/CA 19-9 monoclonal antibody was from LifeSpan Biosciences (Seattle, WA).
