High Performance Probes

Comparative performance of some dye & quencher pairs in qPCR application: for each channel, identical probes (24 bp each) were synthesized and
labeled with selected pairs of dyes and quenchers. The recommended Access™ Probe Pair is highlighted in orange.

Experiments were performed under standard conditions using Takyon™ No Rox Probe Mastermix dTTP from Eurogentec.
