High quality ultraviolet light tables
For the detection of DNA stained with Ethidium Bromide (EtBr), ultraviolet transilluminators are still the most popular choice. When comparing different models of UV tables, the sensitivity of a fluorescence signal is strongly dependent on the quality of the UV lamps and filter platen. Fortunately it is easy to see the difference. Simply put, a high quality UV transilluminator shows almost no visible light, such that when the instrument is switched on the position of the UV lamps should not be easy to detect by eye. If the lamps are visible, this suggest that too much of the long wave-length light is emitted which will result in lower sensitivity (see figure below). Why? The additional visible light increases overall background, reducing the signal-to-noise. The FastGene UV Transilluminator passes this test with flying colors – or should we say pitch black perfection. Don’t regret buying a cheap knockoff.
