Whether your application is gene expression analysis, genotyping, pathogen detection, or other, Sigma's wide selection of reporter and quencher dyes for quantitative PCR (qPCR) probes will support all real-time and end-point detection chemistries.
Dual-Labeled Probes: The most common type, linear hydrolysis probes are used in the 5' nuclease assay.
Molecular Beacons: Structured hybridization probes that are not degraded during the amplification reaction.
LightCycler® Probes: Dual-hybridization probes that are designed for use in Roche™ LightCycler instruments.
Scorpions™ Probes: Combination structured probe – primers that internally hybridize to the target sequence.
