New! Cyanine Nucleic Acid Dyes

Biotium is pleased to offer highly sensitive asymmetric cyanine dyes for nucleic acids. These high quality dyes are identical to popular dyes like SYBR® Green I, YO-PRO®-1, and TOTO®-3 iodide, but at up to half the price of other suppliers. Cyanine nucleic acid dyes are useful for qPCR, gel staining, cell staining, and selective detection of apoptotic and necrotic cells.
