6-ROXtra(TM) fluorescence reference solution *25 uM for PCR reactions*

Ex: 575 nm. Em: 602 nm. Soluble in: Water. 6-ROX is predominately used as a reference dye for performing PCR detections. However, 6-ROX is very unstable compared to other rhodamine dyes. 6-ROXtraT has greatly improved stability and water solubility. 6-ROXtraT has almost identical spectral properties to those of 6-ROX. This 6-ROXtraT dye is 25 uM solution in 20 mM Tris (pH 8.4), 0.1 mM EDTA and 0.01% Tween® 20. 6-ROXtraT dye is stable at room temperature for a few weeks, making this fluorescent dye an excellent replacement to the widely used 6-ROX PCR reference dye.
