EtBr Green Bag^TM
Ethidium bromide safety disposal kit

Ethidium bromide is used routinely by molecular biologists in CsCl gradients and daily in visualization of nucleic acids in gels. This dye intercalates in dsDNA and is classified as a mutagen which requires special care in handling and disposal. Unlike biohazardous wastes, ethidium bromide is not inactivated by either bleach or heat. A convenient means of disposal involves adding activated carbon to solutions containing the dye. After adsorption of the dye to the charcoal, the solution is filtered to remove the charcoal. This process is effective but messy and difficult to perform without contaminating surrounding surfaces. BIO 101 has simplified and optimized this process by adding the best size and most active form of charcoal to a "tea" bag format.

BIO 101's "Green Bag"^® Kit allows rapid and trouble-free concentration of ethidium bromide from large volumes of solutions into a small "tea" bag containing activated carbon which is then conveniently disposed along with other solid hazardous wastes. One kit has the capacity to remove 500 mg of ethidium bromide from solutions (10mg EtBr/bag), enough to satisfy the requirements of most laboratories for a year.
