产品简介

Kerafast抗体Anti-DNA-RNA Hybrid [S9.6] :Anti-DNA-RNA Hybrid [S9.6] Antibody recognizes RNA-DNA hybrids of various lengths.

详细介绍

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

产品介绍:

Kerafast的货号:ENH001,Anti-DNA-RNA Hybrid [S9.6] Antibody,这种小鼠单克隆抗体是针对 ΦX174 噬菌体衍生的合成 DNA-RNA 抗原生成的,可识别各种长度的 RNA-DNA 杂合体。


特色:

可用于检测 R 环

对 DNA-RNA 杂交体的高特异性和亲和力

不与单链 DNA 或双链 DNA 发生交叉反应

对于富含 AU 的双链 RNA,观察到了轻微的交叉反应(约 5 倍以下)。

长度为 8、10、15 和 23 个碱基对的杂交体显示出高亲和力结合


DNA-RNA 杂合体是真核细胞中的一种自然现象,这些杂合体的水平在具有高转录活性的位点增加,例如在转录起始、抑制和延伸期间。由于 RNA-DNA 杂合体会影响基因组的不稳定性,因此 S9.6 抗体是一种有用的试剂,可帮助研究在 DNA 复制或其他细胞过程中由这些杂合体形成的 R 环和损伤的后果。此外,S9.6 抗体可有效识别用于微阵列研究的 RNA-DNA 杂交。


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).
