Inquiry

With the increasing demand and application of oligonucleotide-based diagnostic probes in biomedical research and industrial production, BOC Sciences looks to the global market to provide you with customization and development of dual-labeled probes. Your various dual-labeled probes project needs, such as various modifications or labeling at the 5' end, 3' end, and specified positions are all available at BOC Sciences.

What are Dual Labeled Probes?

Dual-labeled probes, also known as hydrolysis probes, are 20-30 bp DNA or RNA oligonucleotides that are labeled with two different dye groups at the 5' and 3' ends of the probe. Usually the reporter group is located at the 5' end of the dual-labeled probe and the quenching group is located at the 3' end of the dual-labeled probe.

Applications of Dual Labeled Probe

Dual-labeled probes have the advantages of high sensitivity and high specificity, thus realizing accurate quantification in the fields of pathogen detection, gene polymorphism research, and gene mutation detection. Moreover, the features of dual-labeled probes make it possible to perform multiplexed assays to detect multiple target sequences simultaneously.
