    Kerafast抗體Anti-DNA-RNA Hybrid [S9.6] Antibody 

    產品介紹:

    Kerafast的貨號:ENH001,Anti-DNA-RNA Hybrid [S9.6] Antibody,這種小鼠單克隆抗體是針對 ΦX174 噬菌體衍生的合成 DNA-RNA 抗原生成的,可識別各種長度的 RNA-DNA 雜合體。


    特色:

    可用于檢測 R 環

    對 DNA-RNA 雜交體的高特異性和親和力

    不與單鏈 DNA 或雙鏈 DNA 發生交叉反應

    對于富含 AU 的雙鏈 RNA,觀察到了輕微的交叉反應(約 5 倍以下)。

    長度為 8、10、15 和 23 個堿基對的雜交體顯示出高親和力結合


    DNA-RNA 雜合體是真核細胞中的一種自然現象,這些雜合體的水平在具有高轉錄活性的位點增加,例如在轉錄起始、抑制和延伸期間。由于 RNA-DNA 雜合體會影響基因組的不穩定性,因此 S9.6 抗體是一種有用的試劑,可幫助研究在 DNA 復制或其他細胞過程中由這些雜合體形成的 R 環和損傷的后果。此外,S9.6 抗體可有效識別用于微陣列研究的 RNA-DNA 雜交。


    This mouse monoclonal antibody was generated against a ΦX174 bacteriophage-derived synthetic DNA–RNA antigen and recognizes RNA-DNA hybrids of various lengths.

    Highlights:

    * Useful in the detection of R-loops

    * High specificity and affinity for DNA-RNA hybrids

    * Does NOT cross-react with single-stranded DNA or double-stranded DNA

    * Minor cross-reaction (~5-fold less) has been observed for AU-rich double-stranded RNA.

    * High affinity binding shown for hybrids of 8, 10, 15, and 23 base pairs in length

    Tested Applications:

    Dot Blot Analysis: 0.2 µg/mL.
               Affinity Binding Assay: Clone S9.6 bound the DNA-RNA heteropolymer and poly(I)-poly(dC) equally, but 100-fold higher levels of poly(A)-poly(dT) were required to achieve a similar degree of binding. Single-stranded DNA, double-stranded DNA and RNA, and ribosomal RNA were not bound by clone S9.6 (Boguslawski, S.J., et al. (1986). J. Immunol Methods. 89(1):123-130).
               Chromatin Immunoprecipitation (ChIP) Analysis: A representative lot detected increased DNA RNA hybrids at four actively transcribed genes upon shRNA-mediated knockdown of BRCA1 or BRCA2, but not PCID2 or RAD51 in HeLa cells (Bhatia, V., et al. (2014). Nature. 511(7509):362-365).
               Chromatin Immunoprecipitation (ChIP) Analysis: A representative lot detected R-loops formed over beta-actin gene using HeLa chromatin preparation. RNase H treatment of the chromatin preparation prevented clone S9.6 from immunoprecipitating target chromatin fragments (Skourti-Stathaki, K., et al. (2011). Mol. Cell. 42(6):794-805).
               Chromatin Immunoprecipitation-sequencing (ChIP-seq) Analysis: A representative lot detected genome-wide distribution of DNA-RNA hybrids in budding yeast by ChIP-seq analysis (El Hage, A., et al. (2014). PLoS Genet. 10(10):e1004716).
               Immunocytochemistry Analysis: Representative lots immunolocalized nuclear R loops by fluorescent immunocytochemistry staining of methanol-fixed H1 human embryonic stem cells (hESCs) and formaldehyde-fixed HeLa cells (Bhatia, V., et al. (2014). Nature. 511(7509):362-365; Ginno, P.A., et al. (2012). Mol. Cell. 45(6):814-825).
               Immunoprecipitation Analysis: A representative lot immunoprecipitated in vitro transcribed R-loop substrate (DNA-RNA hybrid), but not doouble-stranded DNA (dsDNA) (Ginno, P.A., et al. (2012). Mol. Cell. 45(6):814-825).
