FAQ

Biosearch Technologies offers many common fluorophores including FAM, HEX and TAMRA dyes, as well as our own proprietary dyes. Our CAL Fluor™ and Quasar™ dye series span the spectrum with emission wavelengths ranging from yellow to far-red, and represent alternatives to dyes such as VIC™, Cy™3, Texas Red, LC Red® 640, Cy5, and Cy5.5. For your convenience we have compiled a Multiplexing Dye Recommendations Chart outlining optimal dye combinations in select qPCR machines, as well as a Fluorophore & BHQ™ Dye Selection Chart listing reporter-quencher pairings. In addition, you may use our Spectral Overlay Tool to visualize the absorption and emission spectra of multiple dyes together.
