Product Information
| Description: | Ethidium bromide is an embedded dye used for fluorescent labeling (nucleic acid staining) in molecular biology laboratory science, such as agarose gel electrophoresis. Ethidium bromide intercalates double-stranded DNA and RNA and acts as a frameshift mutagen. It can also be used in conjunction with acridine orange to differentiate between viable, apoptotic and necrotic cells. |
| Stability and Solubility Advice: | Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide. We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials and used within 1 month. Avoid repeated freeze and thaw cycles. Storage conditions for some special products should refer to their storage details. |
