Fig. 2From: Sodium nitrate decreases agrin-induced acetylcholine receptor clusteringExamples of cell cultures exposed to NaNO3. Fluorescent images were captured from agrin-induced cultures that were untreated (a), or exposed for the last 48 h of 72 h in DM to 10 μg/mL NaNO3 (b), 1 μg/mL NaNO3 (c), or 100 ng/mL NaNO3 (d). Fluorescent areas are clusters of AChRs. Scale bar = 100 μmBack to article page
