Fig. 4From: Perovskite Nanoparticles Toxicity Study on Airway Epithelial CellsMucin secretion results after 15-min treatments of increasing LSM concentrations. The ratios were calculated for each LSM concentration by comparing it to the control group. Assessment of cell surface mucin secretions was done by ELLA (enzyme-linked lectin assay).
