proBLUE DNA Stain
Agarose electrophoresis of DNA requires a staining step in order to visualise the DNA fragments. This can be done safely using methylene blue solution. Methylene blue binds to negatively charged DNA making DNA visible as blue bands within agarose following electrophoresis. Methylene blue solution is provided as a 10x concentrate. To use, dilute 10x concentrate by mixing one part of methylene blue with nine parts of water (Eg. 100 ml of 10x concentrate added to 900 ml water).
