ROX Reference Dye for qPCR (A270267)

ROX Reference Dye for qPCR

This ROX formulation is a passive reference dye for qPCR application. The use of this dye is recommended for the normalization of fluorescence intensity of qPCR reporter dyes, such as SYBR Green I or TaqMan probes. It also allows to correct for pipeting errors, and instrumental drift such as change of lamp intensity output over time. The dye contains 25 µM solution of 5-carboxy-ROX (rhodamine-X) reference dye in 10mM Tris-HCl (pH 8.6), 0.1mM EDTA, and 0.01% Tween®-20. ROX reference dye is compatible with all qPCR instruments with ROX channel. Most instruments require either 500 nM or 50 nM end concentration of ROX.
