EPOCH DYES AND QUENCHER
Glen Research’s agreement with Epoch Biosciences, Inc., a subsidiary of Nanogen, Inc., allows us to sell several of Epoch’s proprietary products designed for the synthesis of novel DNA probes. We are pleased to offer products based on Epoch’s Redmond Red™, Yakima Yellow™ and Gig Harbor Green™ fluorophores and Eclipse™ non-fluorescent quencher. Under our agreement we also supply PPG, a modified nucleoside and 5’-Aldehyde-Modifier C2 Phosphoramidite. The two fluorescent dyes, Yakima Yellow and Redmond Red, are available as phosphoramidites and supports. Yakima Yellow has an absorbance maximum at 530 nm and emission maximum at 549 nm, while Redmond Red’s absorbance and emission maxima are at 579 nm and 595 nm, respectively. Gig Harbor Green and 6-FAM are based on the same fluorescein core structure but Gig Harbor Green is 15-20% brighter than FAM.
The Eclipse quencher from Epoch solves most of the problems inherent in the synthesis of molecular beacon and FRET probes. The Eclipse molecule is highly stable and can be used safely in all common oligo deprotection schemes. The absorbance maximum for Eclipse Quencher is at 522 nm, compared to 479 nm for dabcyl. In addition, the structure of the Eclipse Quencher is substantially more electron deficient than that of dabcyl and this leads to better quenching over a wider range of dyes, especially those with emission maxima at longer wavelengths (red shifted) such as Redmond Red and Cy5. In addition, with an absorption range from 390 nm to 625 nm, the Eclipse Quencher is capable of effective performance in a wide range of colored FRET probes.
