TET phosphoramidite for synthesis of fluorescently labeled oligonucleotides, pure 6-isomer.
TET (tetrachlorofluorescein) is a green-fluorescent fluorescein derivate (absorption maximum at 519 nm, emission maximum at 535 nm).
TET phosphoramidite is used for synthesis of fluorescently-labeled primers and hybridization probes for qPCR. TET can be used with DusQ1 fluorescence quencher (can be used with 500 Å DusQ1 CPG 500).
5’-labeled primers are used with non-labeled reverse primers for microsatellite amplification via RCR followed by fragment analysis. TET-labeled amplification products can be analyzed using various sequencers for capillary electrophoresis, including ABI PRISM® 310 Genetic Analyzer.
TET 亚磷酰胺用于合成荧光标记的寡核苷酸,纯 6 异构体。
TET(四氯荧光素)是一种绿色荧光荧光素衍生物(最大吸收波长为 519 nm,最大发射波长为 535 nm)。
TET 亚磷酰胺用于合成荧光标记的引物和用于 qPCR 的杂交探针。 TET 可与 DusQ1 荧光猝灭剂一起使用(可与 500 Å DusQ1 CPG 500 一起使用)。
5′ 标记的引物与未标记的反向引物一起使用,通过 RCR 进行微卫星扩增,然后进行片段分析。 TET 标记的扩增产物可以使用各种毛细管电泳测序仪进行分析,包括 ABI PRISM® 310 遗传分析仪。
Recommendations for using the reagent:
使用试剂的建议:
Condensation: 3 min.
Deprotection: standard conditions with 25% aqueous ammonium solution; deprotection time depends on nucleic base profile and their protective properties (deprotection for 17 hours at 55°C removes all protection groups from standard nucleic acids). AMA (1:1 mixture of concentrated aqueous ammonium/40% aqueous methylamine) can be used with ~5% non-fluorescent by-product forming. To avoid formation of the by-product, start deprotection with ammonium (30 min at room temperature), then add an equivalent volume of 40% aqueous methylamine solution and continue deprotection as usual with AMA (10 min at 65°C).
冷凝:3 分钟。
脱保护:标准条件用25%铵水溶液; 脱保护时间取决于核酸碱基谱及其保护特性(在 55°C 脱保护 17 小时会去除标准核酸中的所有保护基团)。 AMA(浓铵水溶液/40% 甲胺水溶液的 1:1 混合物)可用于形成约 5% 的非荧光副产物。 为避免形成副产物,用铵开始脱保护(室温下 30 分钟),然后加入等量体积的 40% 甲胺水溶液,并像往常一样用 AMA 继续脱保护(65°C 下 10 分钟)。
