We have synthesized and characterized the spectroscopic properties of 56 energy transfer (ET) fluorescent dye-labeled primers differing in (i) the spacing between the donor and acceptor, (ii) the nature of the spacer (either oligonucleotide or polydideoxyribose phosphate), (iii) the primer...

Fluorescence energy transfer (ET) primers are far superior to single dye-labeled primers as labels for DNA sequencing and polymerase chain reaction amplification. We compare here ET primers with different donor and acceptor dye combinations with respect to the relative acceptor...

We report four-color DNA sequencing by synthesis (SBS) on a chip, using four photocleavable fluorescent nucleotide analogues (dGTP-PC-Bodipy-FL-510, dUTP-PC-R6G, dATP-PC-ROX, and dCTP-PC-Bodipy-650) (PC, photocleavable; Bodipy, 4,4-difluoro-4-bora-3alpha,4alpha-diaza-s-indacene; ROX, 6-carboxy-X-rhodamine; R6G, 6-carboxyrhodamine-6G). Each nucleotide analogue consists of a different fluorophore attached to...
