ROX Reference Dye for qPCR

7

570 nm

Research Use Only

95% (by 1H NMR and HPLC-MS).

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 microM 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.

Shipped at room temperature. Upon delivery, store in the dark at -20°C. Avoid prolonged exposure to light.
