GRRed nucleic acids loading buffer contains GR Red Nucleic Acid Stain, a safe and highly sensitive fluorescent dye that enables instant band visualization during or immediately after running your agarose gel. Supplied in 6X loading buffer, it forms a tight complex with the sample nucleic acids and comigrates with nucleic acids during electrophoresis. After the run, simply place the gel on a standard UV to view nucleic acids bands. No post staining or destaining is required. GRRed provides a faster, safer, environmental friendly alternative to ethidium bromide.

Safe: GRRed is non-mutagenic in Ames tests performed by an independent testing laboratory. Your lab will not have to deal with hazardous EtBr waste: you can simply dispose the gel as regular trash.

Easy: Supplied in 6X loading buffer, simply mix loading buffer with nucleic acids sample (e.g., add 2 µl of the loading buffer to 10 µl nucleic acids sample), run on gel, and visualize bands using a UV transilluminator (no post staining required).

Sensitive: GRRed is more sensitive than ethidium bromide and SYBR Safe.

Economical: No hazardous shipping and storage charges or expensive waste treatment.

Storage and Handing

GRRed is supplied as a 6X loading buffer. For long-term storage the buffer should be stored at -20 ℃ protected from light. It is stable for 1 year at -20 ℃ and 3 months at 4 ℃.

GRRed dye can be completely removed from nucleic acids by alcohol precipitation or Qiagen QIAquick Gel Extraction.

DNA Staining Protocol

Add 2 µl of the 6X loading buffer to 10 µl DNA sample and DNA marker/ladder. Load samples and run the gel using your standard protocol. View DNA bands using a UV transilluminator.
