核酸酶靶向切割和釋放 (CUT&RUN)是建立在免疫探測技術(shù)上的染色質(zhì)圖譜分析方法。在CUT&RUN中，融合蛋白AG-微球菌核酸酶（pAG-MNase），選擇性原位切割抗體結(jié)合的染色質(zhì)（Figure 1）。該方法與二代測序（NGS）兼容，可提供組蛋白翻譯后修飾（PTMs）和染色質(zhì)相關(guān)蛋白（如轉(zhuǎn)錄因子[TFs]）的高分辨率全基因組圖譜。

產(chǎn)品優(yōu)勢
?CUTANATM?Library Prep Kit 是第一個專門為CUT&RUN分析開發(fā)的文庫構(gòu)建試劑盒。
?對CUT&RUN的方法進行了優(yōu)化，對比多用途或ChIP-seq文庫構(gòu)建試劑盒更具優(yōu)勢。
?對于CUT&RUN產(chǎn)生的有限輸入，工作流程非常穩(wěn)定，為使用0.5-10?ng DNA的Illumina??NGS提供了高質(zhì)量的文庫。
?試劑盒包含CUT&RUN文庫制備所需的所有材料（酶、引物、DNA純化磁珠、緩沖液和PCR管）。
?可輕松搭配CUTANA? CUT&RUN試劑盒（EpiCypher 14-1048）或CUT&RUN Protocol （EpiCypher.com/protocols）使用，實現(xiàn)工作流程集成，高通量檢測和保證結(jié)果的可靠性，降低實驗成本。
?可以有效制備組蛋白PTMs和染色質(zhì)相關(guān)蛋白（如TFs）CUT&RUN DNA的文庫。

FIGURE 1： CUT&RUN DNA Fragment Size Distribution Analysis. CUT&RUN was ?performed as described above.?Library DNA was ?analyzed by Agilent TapeStation? , which ?confirmed that mononucleosomes were??predominantly enriched in CUT&RUN (~300 bp ?peaks represent 150 bp nucleosomes + ?sequencing?adapters). Peaks at ~380 bp ?correspond to the SNAP-CUTANA??K-MetStat Panel of spike-in controls(EpiCypher 19-1002). |

FIGURE 2： Representative Gene Browser Tracks. CUT&RUN was performed as described above. A representative?674 kb window at the SEPTIN5 gene is shown for three replicates (”Rep”) of IgG and H3K4me3 antibodies,?as well as individual tracks for H3K27me3 and the transcription factor CTCF, demonstrating the robustness?and reproducibility of the workflow with a variety of targets. Sequencing libraries prepared with the CUTANA?CUT&RUN Library Prep kit produced the expected genomic distribution for each target. Images were generated?using the Integrative Genomics Viewer (IGV, Broad Institute) |
