5-ROX is the purified isomer of 5(6)-ROX. It is preferred for some complicated biological applications where reproducibility is really critical. The minor positional difference between 5-ROX and 6-ROX might significantly affect some biological properties of the underlying conjugates. Used for oligonucleotide labeling and automated DNA sequencing applications. ROX is a passive fluorescent dye used in real-time PCR (qPCR) for signal normalisation. By normalising the fluorescent signal, this can reduce the variability between technical replicates.
