The UElandy GelstainRedTM S2009S/S2009L nucleic acid stain manual provides product details, storage guidelines, and gel staining procedures.
GelstainRedTM is a high‑sensitivity, non‑mutagenic fluorescent nucleic‑acid gel staining reagent that can replace ethidium bromide (EtBr) with comparable spectral properties. It is supplied as a 10,000× stock solution in water and is available in 0.1 mL and 0.5 mL vials (product numbers S2009S, S2009L).
The manual describes two staining methods: direct incorporation into agarose gels and post‑electrophoresis soaking (bubble staining). It also gives storage conditions (room temperature) and safety notes, including how to resolve precipitation and the reduced sensitivity for single‑stranded nucleic acids. This manual is written in Chinese.

Dilute the stock about 3,300‑fold in water to make a 3× staining solution, e.g., 15 µL of stock in 50 mL water.
Store at room temperature; if precipitation occurs, heat the dye to 45‑50 °C for 2 minutes and vortex to dissolve.
Yes, it can stain single‑stranded DNA and RNA, but its sensitivity for these is lower than for double‑stranded DNA.
