Black Hole Quencher (BHQ) dyes are dark quencher dyes that quenches fluorescent signals with greater efficiency and specificity, giving you the power to unlock new insights and get your product to market faster. You can purchase BHQ dyes in CPG or amidite form to manufacture probes in house, or you can purchase custom BHQ probes synthesized by LGC Biosearch Technologies.
learn moreRecently issued a patent for its CAL Fluor™ dyes, we introduced this series of vibrant dyes for real-time qPCR as lower-cost, superior performing replacements for many commonly used fluorophores. Their emission maxima range from 544 nm to 637 nm, which make them ideal fluorophores for multiplexed qPCR. They are excellent replacement fluorophores for VIC, TET, HEX, JOE, TAMRA, Texas Red®, LC Red 640® dyes. We offer dye calibration standards to optimise your instruments performance for these dyes.
learn moreThe Quasar™ Dyes were developed as replacements for the Cy™ dyes. These high performing, lower cost dyes facilitate the automated synthesis of probes. With emission values ranging from 566 to 705 nm, Quasar dyes increase fluorophore choices and help eliminate potential cross-talk problems associated with multiplex qPCR and are efficiently quenched by BHQs.
learn moreLGC, Biosearch Technologies offers CAL Fluor™ and Quasar™ dyes that span a wide range of emission wavelengths, for maximum flexibility in experimental design. Dye calibration standards are formulated with the fluorophore covalently attached to an oligo-dT (10-mer), to better mimic the signal from a fluorescent probe.
learn moreSuperROX is a specially formulated version of the ROX dye (carboxy-X-rhodamine) for use as a passive reference in qPCR reactions. It is typically formulated into the master mix, and used to normalize for signal variation on certain real-time thermal cyclers.
