Li-Cor Biosciences D-DiGit Gel Scanner

Li-Cor Biosciences has launched the LED-based D-DiGit Gel Scanner, designed to help researchers eliminate the risk of ethidium bromide exposure and workspace contamination from their nucleic acid gel analysis experiments. The new system enables safe and convenient detection of DNA and RNA samples stained with fluorescent safe stains, like SYBR Safe, which are sensitive and environmentally friendly alternatives to ethidium bromide. Added either during gel preparation, or as a post-electrophoresis stain, safe stains eliminate the need for hazardous disposal and hassles associated with ethidium bromide. The D-DiGit improves protocol efficiency by consolidating nucleic acid analysis on a single system dedicated to high-sensitivity gel imaging. The scanner provides a large scan area to visualize most medium and larger format gels. Nucleic acid band extraction and imaging can be performed directly on the scan surface, the company said.
