Example Alt Text
"Gel electrophoresis image shows molecular size ladders at both ends and multiple unlabeled sample lanes. Each lane contains one prominent band at a different migration distance, with several faint secondary bands and light smearing in the upper regions. Band positions vary across the lanes, indicating samples with different fragment sizes."
