SYBR Green II RNA gel stain is a sensitive nucleic acid gel stain that has bright fluorescence when bound to RNA and low background in gels, making it ideal for use with either formaldehyde/agarose or polyacrylamide gels using laser scanners or standard UV transilluminators. A 500 µL unit size (S-7564) and 1mL unit size (S-7568) are available.
