Experimental details: Immunofluorescent analysis of CDw75 (green) showing staining in the membrane and cytoplasm of BAF-3 cells (right) compared to a negative control without primary antibody (left). Formalin-fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 5-10 minutes and blocked with 3% BSA-PBS for 30 minutes at room temperature. Cells were probed with a CDw75 monoclonal antibody (Product # MA5-11900) in 3% BSA-PBS at a dilution of 1:20 and incubated overnight at 4ºC in a humidified chamber. Cells were washed with PBST and incubated with a DyLight-conjugated secondary antibody in PBS at room temperature in the dark. F-actin (red) was stained with a fluorescent red phalloidin and nuclei (blue) were stained with Hoechst or DAPI. Images were taken at a magnification of 60x.

Experimental details: Flow cytometry analysis of CDw75 in BAF-3 cells (green) compared to an isotype control (blue). Cells were harvested, adjusted to a concentration of 1-5x10^6 cells/mL, fixed with 2% paraformaldehyde and washed with PBS. Cells were blocked with a 2% solution of BSA-PBS for 30 min at room temperature and incubated with a CDw75 monoclonal antibody (Product # MA5-11900) at a dilution of 2 µg/test for 60 min at room temperature. Cells were then incubated for 40 min at room temperature in the dark using a Dylight 488-conjugated secondary antibody and re-suspended in PBS for FACS analysis.

Experimental details: Flow cytometry analysis of CDw75 in PBMC cells (green) compared to an isotype control (blue). Human blood was collected, combined with a hydrophilic polysaccharide, centrifuged, transferred to a conical tube and washed with PBS. 50 µL of cell solution was added to each tube at a dilution of 2x10^7 cells/mL, followed by the addition of 50 µL of isotype control and primary antibody (Product # MA5-11900) at a dilution of 2 µg/test. Cells were incubated for 30 min at 4ºC and washed with a cell buffer, followed by incubation with a DyLight 488-conjugated secondary antibody for 30 min at 4ºC in the dark. FACS analysis was performed using 400 µL of cell buffer.

Experimental details: Figure 5 Inhibition of ST6GAL1 secretion reduces alpha2-6 sialylation and increases IL-6 secretion similar to CSE. (A) Flow cytometric analysis of alpha2-6 sialylation using SNA-FITC labeling of HBECs (CTRL, ST6GAL1 KD, and ST6GAL1 OE) following treatment with and without iBACE and CSE for 72 hours. (B) 10,000 events were collected for each group, analyzed, and shown as the geometric mean. (C) Densitometry and a representative slot blot of secreted ST6GAL1 collected from conditioned medium following incubation with iBACE, CSE, or both. As a loading control, the supernatants were normalized to total cellular protein. (D) IL-6 secretion was determined from conditioned medium using an ELISA kit to the IL-6 ligand following same treatments as (C) . Experiments were performed in triplicate using three separate experiments. SNA, Sambucus Nigra Lectin; CTRL, control; iBACE, beta-site amyloid precursor protein cleaving enzyme 1 inhibitor; and CSE, cigarette smoke extract. All bar graphs are means +- SEM with *p < 0.05, **p < 0.01 and ***p < 0.001.
