If you're doing a lot of DNA or RNA isolation - and likely fragment recovery - you probably use a transilluminator to find your bands. Staining aside, most conventional illuminators rely on UV-based imaging to generate fluorescent response from the dyes. UV can cause damage to the DNA of interest, but can also be harmful to the operator's eyes and skin. Look to replacing your UV imager with an LED one: not only are the LEDs safe for you to be exposed to, but their light source lasts 5x longer than standard UV bulbs. Environmentally and economically minded is the best way to be labconscious! Check out these FastGene products, made by Nippon Genetics and available stateside at Bulldog Bio
