GelStain is the perfect and safe alternative to ethidium bromide staining of DNA or RNA during agarose el electrophoresis. It is a sensitive, stable and safe staining reagent for DNA/RNA. This DNA/RNA stain uses the same wavelength as ethidium bromide (EtBr), and it is more sensitive than EtBr.

Advantages of using GelStain

  • No toxicity: made of a unique mixture of hydrophobic macromolecules. GelStain does not penetrate cell membranes.
  • High sensitivity: provides high sensitivity, detecting low amounts of DNA or RNA (10-20 ng).
  • Exceptional stability: can be heated or microwaved.
  • Signal to noise ratio: strong fluorescent signal from samples, weak from background.
  • Like EtBr, GS101 can be used before electrophoresis or after electrophoresis. No destaining is needed.
  • No optical setting change: standard EB filter and SYBR filter can be used.
