Human bronchial epithelial cells were lysed in lysis buffer and subjected to SDS-PAGE and a Western blot analysis38 (link). Blots were reacted for 2 h with monoclonal antibody diluted at 1:1000 and with the respective HRP-conjugated secondary antibodies diluted at 1:2000. After each antibody reaction, membranes were washed 3 times with 0.1% TBS-Tween, and blots were visualized with Super Signal West Pico chemiluminescence substrate (Thermo Fisher Scientific, Inc.). Images were captured by LAS-4000 (GE HealthCare Dharmacon, Inc.). The band intensity was quantified using the Multi Gauge software program (FUJIFILM, Inc., Tokyo, Japan). For the detection of MUC5AC protein secretion into the medium, slot blotting was performed as previously described39 (link).

Cultured Colon26 cells (10
6cells) were homogenized with a lysis buffer containing 0.5% Nonidet P-40, 10% glycerol, 137 mM NaCl, 2 mM ethylenediaminetetraacetic acid, and 50 mM Tris-HCl buffer (pH 8.0). After centrifugation at 8,000 × 
gfor 10 minutes, the supernatant fraction was collected, and the total protein concentration of the cell extract was measured using Bradford Protein Assay Kit (Bio-Rad Laboratories, Hercules, California, United States) and stored at −80°C until analysis. Samples (0.25–2.5 μg total protein/lane) were subjected to 10% polyacrylamide gel electrophoresis in the presence of 0.1% sodium dodecyl sulfate. The electrophoresed protein was transferred to an Immobilon membrane (Life Technologies, Carlsbad, California, United States), subsequently blocked with 5% skim milk at 4°C overnight, and incubated with anti-mouse TF monoclonal antibody (1:1,000; Bioss Antibodies Inc., Woburn, Massachusetts, United States) at 25°C for 1 hour. The membrane was then treated with a horseradish peroxidase-conjugated secondary antibody (Novex, Frederick, Maryland, United States). Immune complexes were detected using ImmunoStar Zeta regent (Wako, Osaka, Japan), and images were acquired using the Multi-Gauge software program (Fujifilm, Greenwood, South Carolina, United States).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
