  Solid- and solution-phase synthesis and application of R6G dual-labeled oligonucleotide probes

  摘要：

  A novel N-TFA-protected carboxyrhodamine 6G (R6G) phosphoramidite was synthesized for use in an automated DNA synthesis to prepare 5'-labeled oligonucleotides. Deprotection and purification conditions were optimized for 5'-labeled and dual-labeled oligonucleotide probes. As an alternative we synthesized an azide derivative of R6G for CuAAC post-synthetic oligonucleotide labeling. Dual-labeled probes obtained by both methods showed the same efficacy in a quantitative PCR assay. R6G-labeled probes demonstrated superior properties in a qPCR assay in comparison with alternative HEX, JOE and SIMA dyes due to more efficient fluorescence quenching by BHQ-1. We successfully used R6G dual-labeled probes for rotavirus genotyping. (c) 2015 Elsevier Ltd. All rights reserved.
