No more guesswork – Accurately measure the mobility of electrophoretic markers and ethidium bromide-DNA complexes during electrophoresis
Thin - At 7 mm wide they require only a single lane of an agarose gel
Fluorescent ink markings are sharp and photograph well under UV light (300nm & 350nm)
Rulers are made of a flexible, UV-clear plastic so only the fluorescent markings will show under UV light
