Glowing Gel Electrophoresis Under Blue Hood

Bright orange DNA bands stretch horizontally across a translucent agarose gel, illuminated by the cool violet glow of a dark blue transilluminator hood. Condensation beads along the curved interior of the glass enclosure, catching the north-window sidelight that floods the university research lab in Ciudad Ojeda during midmorning. The dry season air leaves the glass surfaces sharp and clear except for the faint moisture clinging to the edges. A gloved hand hovers just above the gel, fingers poised to extract a sample with a fine pipette tip. The plastic tray beneath the gel reflects the blue light, creating a soft gradient that fades into the white laboratory bench. A small yellow label on the tray reads 'Run 4' in black ink.
