inert dye for real-time pcr

"I'm looking for an inert dye to add to my colorless real-time pcr
mixes to be able to check the performance of a pipetting robot."



There are published reports of two different red dyes used for this
purpose.



1) 0.01% Phenol red (R. J. Klebe, S. A. Rodriguez, M. L. VerBeek and T.
A.

Giambernardi, 1999. Simple method for "hot-start" RT-PCR.

BioTechn. 27(6):1108-1110.)



2) Carl Wittwer's laboratory uses 0.1 mM Cresol Red for the same purpose


(The Rapid Cyclist, Spring, 1994, page 9).

Since PCR mix is H2O based you can try any number of food color dyes,
provided that they wont interfere with the emission/excitation spectra
of your real-time detection system.
