Thermo Scientific™ Pierce Ethidium Bromide is available as both dilute (0.625mg/mL) and more concentrated (10mg/mL) solutions to accommodate most molecular biology applications for fluorescent DNA visualization.
0.625mg/mL EtBr Solution:
Each drop contains 25μg of ethidium bromide and is ideal for a 50mL agarose gel
After adding one drop of solution per 50mL of gel, the final concentration of EtBr will be 0.5μg/mL, which is the recommended concentration for electrophoresis of nucleic acids
Can also be used as the running buffer or for staining gels after electrophoresis
10mg/mL EtBr Solution:
A safe and convenient way to use ethidium bromide while minimizing exposure
