產(chǎn)品簡介

HighYield T7 AF488 RNA標(biāo)記試劑盒設(shè)計用于通過體外轉(zhuǎn)錄隨機(jī)產(chǎn)生AF488修飾的RNA探針。這種探針非常適合原位雜交和Northern Blot實驗。AF488(也稱為Alexa Fluor?488)是一種親水性染料,與熒光素相比,其光穩(wěn)定性更強(qiáng)。

UTP-PEG5-AF488使用優(yōu)化的反應(yīng)緩沖液和T7 RNA標(biāo)記聚合酶混合物有效地并入RNA中,作為天然對應(yīng)物UTP的替代物。35%UTP-PEG5-AF488替代通常會在反應(yīng)和標(biāo)記效率之間實現(xiàn)最佳平衡。然而,UTP-PEG5-AF488/UTP比值的單獨優(yōu)化可以通過單核苷酸格式輕松實現(xiàn)。由此產(chǎn)生的AF488修飾RNA探針隨后可以通過熒光光譜檢測。

該試劑盒含有足夠的試劑,用于20個標(biāo)記反應(yīng),每個反應(yīng)20μl(35%UTP-PEG5-AF488替代物、2.5 mM ATP、GTP、CTP、0.2 mM UTP、0.1 mM UTP-PEG-5-AF488.)。

培養(yǎng)30分鐘后,20μl反應(yīng)產(chǎn)生約5-7μg RNA(1μg T7對照模板,1.4 kb RNA轉(zhuǎn)錄物)。然而,產(chǎn)量可能因模板而異(啟動子設(shè)計、序列長度、二級結(jié)構(gòu)形成)。
