Kerafast ENH001 Anti-DNA-RNA Hybrid [S9.6] Antibody 针对ΦX174噬菌体衍生的合成DNA-RNA抗原产生该小鼠单克隆抗体,并识别各种长度的RNA-DNA杂交体。
产品特色:
- 对DNA-RNA杂交体具有高度特异性和亲和力
- 可用于检测R环
- 不与单链DNA或双链DNA交叉反应
- 对于富含AU的双链RNA,已观察到轻微的交叉反应(约5倍)。
- 对于长度为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天然存在,这些za种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杂交体影响基因组不稳定性,S9.6抗体是一种有用的试剂,可帮助研究这些za种在DNA复制或其他细胞过程中形成的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。
背景介绍:
DNA-RNA hybrids are a natural occurrence within eukaryotic cells, with levels of these hybrids increasing at sites with high transcriptional activity, such as during transcription initiation, repression, and elongation. Because RNA-DNA hybrids influence genomic instability, the S9.6 antibody is a useful reagent to help study the consequences of R-loops and lesions formed by these hybrids during DNA replication or other cellular processes. In addition, the S9.6 antibody is effective in recognizing RNA-DNA hybridization for microarray studies。

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).
