agarose gels are precast bufferless gels with electrodes embedded in the agarose matrix. Each
gel contains an ion generating system, a pH balancing system, and DNA stain packaged inside a
transparent plastic cassette. Each gel cassette contains two ion exchange matrices (IEMs) that are in
contact with the gel and electrodes. The IEMs supply a continuous flow of ions throughout the gel
resulting in a sustained electric field required for running the gel.

SYBR
™
Safe DNA gel stain
SYBR
™
Safe DNA gel stain has been specifically developed for reduced mutagenicity, making it safer
than ethidium bromide for staining DNA in agarose gels. The detection sensitivity of E

™
with SYBR
™
Safe stain is similar to that of E

containing ethidium bromide. DNA bands stained with SYBR
™
Safe DNA gel stain can be detected by standard UV transillumination, visible-light transillumination, or
laser-scanning.
Disposal
SYBR
™
Safe DNA gel stain is not classified as hazardous waste, but because disposal regulations vary,
please contact your safety office or local municipality for appropriate SYBR
™
Safe disposal in your
community.
