RNA乙酰化修飾:ac4C測序 acRIP-seq
項目簡介
acRIP-seq
N4-acetylcytidine (ac4C),N4位乙酰胞嘧啶,是真核原核生物中保守的化學修飾,早期研究認為ac4C主要存在tRNA和18S rRNA上。而近期研究顯示,mRNA上也存在大量的ac4C,該修飾在促進蛋白翻譯,影響RNA穩定性和可變剪接,調控基因表達發揮重要作用,有望成為表觀轉錄組學的新興發展方向。
表觀生物ac4C免疫共沉澱測序服務(acRIP-seq),全麵解析ac4C在轉錄組的分布及變化,幫助科研人員深入理解RNA乙酰化在生命和疾病中的作用,促進疾病的精準診斷與治療研究。
項目流程
RNA乙酰化免疫共沉澱 (acetylated RNA Immunoprecipitation,acRIP)基於抗體特異性結合乙酰化修飾的堿基的原理,以RNA免疫共沉澱富集乙酰化修飾片段為基礎,然後通過高通量測序,在全轉錄組範圍內研究發生乙酰化的RNA區域,高效獲得結果。
