產品介紹(shao)：

Kerafast的(de)(de)(de)貨號：ENH001，Anti-DNA-RNA Hybrid [S9.6] Antibody，這種小鼠單克隆抗體是(shi)針對(dui) ΦX174 噬菌體衍生(sheng)的(de)(de)(de)合(he)(he)成(cheng) DNA-RNA 抗原生(sheng)成(cheng)的(de)(de)(de)，可識別(bie)各種長度的(de)(de)(de) RNA-DNA 雜(za)合(he)(he)體。

特色(se)：

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(dan)鏈 DNA 或(huo)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(ying)（約 5 倍以下）。

長度為 8、10、15 和 23 個堿基對(dui)的(de)雜(za)交體顯示出高(gao)親和力結合

DNA-RNA 雜(za)合(he)體是真核細胞中的一種(zhong)(zhong)自然(ran)現象(xiang)，這些雜(za)合(he)體的水平在(zai)具有高轉(zhuan)錄活(huo)性的位點增加，例如在(zai)轉(zhuan)錄起始、抑(yi)制(zhi)和延(yan)伸期間。由(you)于(yu)(yu) RNA-DNA 雜(za)合(he)體會影響基(ji)因組(zu)的不穩定性，因此(ci) S9.6 抗(kang)體是一種(zhong)(zhong)有用的試劑，可幫助研究(jiu)在(zai) DNA 復制(zhi)或其他細胞過程中由(you)這些雜(za)合(he)體形成的 R 環和損傷的后(hou)果(guo)。此(ci)外，S9.6 抗(kang)體可有效識別用于(yu)(yu)微陣列(lie)研究(jiu)的 RNA-DNA 雜(za)交(jiao)。

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

Antigen:	S9.6 ΦX174 bacteriophage-derived synthetic DNA–RNA antigen
Isotype:	Rabbit IgG
Fusion Tag(s):	Mouse Fab version contains His-tag
Clone Name:	S9.6
Reactivity:	High specificity and affinity for DNA/RNA hybrids and other A-form nucleic acid hybrids
Immunogen:	ΦX174 bacteriophage-derived synthetic DNA/RNA
Purification Method:	Protein A/G
Buffer:	ENHOO1: PBS, 0.05% (w/v) Sodium Azide Ab01137- : PBS with 0.02% Proclin 300
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).
