Imaging DNA and protein gels
For analysing DNA and RNA routinely in your lab, having a great gel doc (gel documentation) system is critical. DNA/RNA stained with ethidium bromide is often visualised using UV. When you need to re-use that DNA, for example, you can choose safer dyes such as SYBR® Safe, SYBR® Gold, SYBR® and GelGreen® which can be imaged with blue light.
If you’re looking for proteins on gels, you can easily visualise bands stained with Coomassie blue or silver stain.
