產(chǎn)品簡介

HighYield T7 AF647 RNA標記試劑盒旨在通過體外轉(zhuǎn)錄產(chǎn)生隨機的AF647修飾RNA探針。這種探針非常適合原位雜交和Northern Blot實驗。AF647（Alexa Fluor?647的結(jié)構(gòu)類似物）是一種親水性染料，與Cy5相比，其光穩(wěn)定性更強。

UTP-PEG5-AF647使用優(yōu)化的反應(yīng)緩沖液和T7 RNA標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-AF647替代通常會在反應(yīng)和標記效率之間實現(xiàn)最佳平衡。然而，UTP-PEG5-AF647/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AF647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個標記反應(yīng)，每個反應(yīng)20μl（35%UTP-PEG5-AF647替代物、2.5 mM ATP、GTP、CTP、0.2 mM UTP、0.1 mM UTP-PEG-5-AF646）。20μl反應(yīng)在30分鐘培養(yǎng)后產(chǎn)生約4-6μg 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）。
