Biosearch Technologies, Inc., located in northern California, is an ISO 9001:2008 certified manufacturer of sophisticated oligonucleotides for real-time qPCR applications. Since its founding in 1993, Biosearch has been at the forefront of advancing nucleic acid technology with the invention of CAL Fluor® and Quasar® fluorophores, and the Black Hole Quencher® (BHQ®) series of dyes – the industry standard in full spectrum quenchers for real-time qPCR.

Biosearch produces a variety of probe formats, including Dual-Labeled BHQ® Probes, BHQplus™ Probes, Molecular Beacons, and Scorpions® Primers. Picking the right probes and primers is made easy through Biosearch’s free RealTimeDesign™ software, a web-based qPCR assay design application for gene expression analysis, SNP genotyping, and multiplexed qPCR.

Biosearch also offers Stellaris RNA FISH probes, a new research technology that enables simultaneous detection, localization and quantification of RNA. This much improved FISH technology makes use of multiple single-labeled oligonucleotide probes to provide a high degree of specificity and sensitivity. The low cost per assay, simple protocol, and the ability to localize mRNA and lncRNA to organelles and cellular structures provides obvious benefits for life science research. Custom and catalogued probes sets available.
