Product details

Non-toxic and non-carcinogenic dyes for fluorescent staining of nucleic acids in agarose gels and polyacrylamide gels. Highly sensitive and applied just like ethidium bromide.

The ROTI®GelStain dyes are used as additives to the gel solution and the running buffer, partly also post-run staining is possible. Both ROTI®GelStain dyes can be excited by UV light, additionally, ROTI®GelStain Red may be excited by blue light. Resulting signals may be detected by ethidium bromide broadband photo filters.

ROTI®GelStain 20 000x conc., ready-to-use

ROTI®GelStain is a versatile staining reagent for detection of all nucleic acids in agarose and polyacrylamide gels.

  • Green fluorescence
  • Alternative for ethidium bromide, non-toxic and non-mutagenic
  • For dsDNA, ssDNA and RNA
  • Sensitivity comparable to ethidium bromide (approx. 0.3 ng / band)
  • For use with common broad-band ethidium bromide photo filters
  • Excitation via UV light (302 nm) and blue light (490 nm)
  • Compatible with all usual down-stream applications

The dye can be used in a similar manner as ethidium bromide. By adding the dye to the liquid gel, the nucleic acids are stained during the gel run.

ROTI®GelStain has a sensitivity of 0.2 ng/band and is thus even slightly more sensitive than ethidium bromide.
When bound to nucleic acids in agarose gels, ROTI®GelStain emits a brightly green fluorescence that may be documented by all usual broadband ethidium bromide or SYBR® Green foto filters.

ROTI®-GelStain is compatible with all standard down-stream applications and has been successfully tested for use with gel extraction, ligation, transformation and transfection.

Amplicons of a mouse genotyping (left), and restriction digested DNA (right), respectively, separated in 2,5 and 1 % agarose ROTI®Garose NEEO with ROTI®GelStain (5 µl / 100 ml agarose). Pictures were taken using standard ethidium bromide photo filters.
