Description

Recommended products
Adipic Acid 99%

Application
Ethidium bromide (EtBr) is the most commonly used nucleic acid stain for PAGE or agarose gel electrophoresis. The fluorescence of EtBr increases 21-fold upon binding to double-stranded RNA and 25-fold on binding double-stranded DNA so that destaining the background is not necessary with a low stain concentration (10gml).

Purpose
For R&D use onlynot for drug household or other uses.

General Description
Ethidium bromide is an intercalating agent commonly used as a fluorescent tag (nucleic acid stain) in molecular biology laboratories for techniques such as agarose gel electrophoresis. It is commonly abbreviated as EtBr which is also an abbreviation for bromoethane. When exposed to ultraviolet light it will fluoresce with an orange colour intensifying almost 20-fold after binding to DNA.
