SUMMARY
In Southern blotting, DNA bands can be visualized using two distinct methods: ethidium bromide (EtBr) staining and DNA probes. Ethidium bromide is a non-specific stain that binds to all DNA, allowing for general visualization. In contrast, DNA probes are utilized for the specific detection of complementary base pair sequences, making them suitable for targeted analysis. Each method serves a unique purpose and is applied in different experimental contexts.
