    Product Usage Information

    For optimal ChIP and ChIP-seq results, use 10 μl of antibody and 10 μg of chromatin (approximately 4 x 106 cells) per IP. This antibody has been validated using SimpleChIP® Enzymatic Chromatin IP Kits. The CUT&Tag dilution was determined using 100,000 cells in a total reaction volume of 100 μl.

    Specificity/Sensitivity

    仅在 Lys9 位点上被二甲基化时，Di-Methyl-Histone H3 (Lys9) (D85B4) XP™ Rabbit mAb 才能检测出组蛋白 H3 的内源水平。该抗体不会与未甲基化、单甲基化或三甲基化组蛋白 H3 Lys9 发生交叉反应。此外，该抗体不会与在 Lys4、Lys27 或 Lys36 上双甲基化的组蛋白 H3 和在 Lys20 上双甲基化的组蛋白 H4 发生交叉反应。

    背景
    背景
    核小体由四个核心组蛋白（H2A、H2B、H3 和 H4）组成，是染色质的主要组成部分。最初被认为可作为 DNA 包装的静态支架的组蛋白现在已被证明是动态蛋白，可进行多种类型的翻译后修饰，包括乙酰化、磷酸化、甲基化和泛素化 (1)。组蛋白甲基化是形成基因组的活跃和非活跃区域的主要决定因素，并且在发育期间基因组的正确编程过程中发挥关键作用 (2,3)。组蛋白 H3 (Arg2, 17, 26) 和 H4 (Arg3) 的精氨酸甲基化可促进转录激活，并由蛋白精氨酸甲基转移酶 (PRMTs) 家族介导，该家族包括辅助激活因子 PRMT1 和 CARM1 (PRMT4) (4)。与此相反，已确定更多样化的组蛋白赖氨酸甲基转移酶，除了其中某个外其余的都含有一个保守催化 SET 结构域，该结构域最初在果蝇 Su(var)3-9、zeste 增强子和 Trithorax 蛋白中得以确认。赖氨酸甲基化主要发生在组蛋白 H3 (Lys4 位点, 9, 27, 36, 79) 和 H4 (Lys20 位点) 中，并已确定与转录激活和沉默有关 (4)。这些赖氨酸残基的甲基化可协调染色质修饰酶的募集，这些酶含有甲基赖氨酸结合模块，例如克罗莫结构域 (HP1, PRC1)、PHD fingers (BPTF, ING2)、tudor 结构域 (53BP1) 和 WD-40 结构域 (WDR5) (5-8)。PADI4、LSD1、JMJD1、JMJD2 和 JHDM1 等组蛋白脱甲基酶的发现表明：甲基化是可逆的表观遗传标记物 (9)。 1.Peterson, C.L. and Laniel, M.A. (2004) Curr Biol 14, R546-51. 2.Kubicek, S. et al.

    Western blot analysis of extracts from various cell lines using Di-Methyl-Histone H3 (Lys9) (D85B4) XP™ Rabbit mAb.

    使用Di-Methyl-Histone H3 (Lys9) (D85B4) XP™ Rabbit mAb兔单抗，免疫印迹(Western blot)分析不同细胞中Di-Methyl-Histone H3 (Lys9)蛋白水平。

    Di-Methyl Histone H3 (Lys9) (D85B4) XP™ Rabbit mAb specificity was determined by peptide ELISA. The graph depicts the binding of the antibody to pre-coated di-methyl histone H3 (Lys9) peptide in the presence of increasing concentrations of various competitor peptides. As shown, only the di-methyl histone H3 (Lys9) peptide competed away binding of the antibody.

    通过peptide ELISA确定Di-Methyl Histone H3 (Lys9) (D85B4) XP™ Rabbit mAb的特异性。该图描述了抗体与提前包被的di-methyl histone H3 (Lys9) peptide的结合能力，并且多肽中含有浓度递增的不同竞争多肽。如同所示，仅di-methyl histone H3 (Lys9) peptide竞争脱离抗体的结合。

    Chromatin immunoprecipitations were performed with cross-linked chromatin from 4 x 106 HeLa cells and either 20 μl of Di-Methyl-Histone H3 (Lys9) (D85B4) XP® Rabbit mAb or 2 μl of Normal Rabbit IgG #2729 using SimpleChIP® Enzymatic Chromatin IP Kit (Magnetic Beads) #9003. The enriched DNA was quantified by real-time PCR using SimpleChIP® Human GAPDH Exon 1 Primers #5516, SimpleChIP® Human RPL30 Exon 3 Primers #7014, SimpleChIP® Human AFM Intron 1 Primers #5098, and SimpleChIP® Human α Satellite Repeat Primers #4486. The amount of immunoprecipitated DNA in each sample is represented as signal relative to the total amount of input chromatin, which is equivalent to one.

    使用SimpleChIP®Enzymatic Chromatin IP Kit (Magnetic Beads) #9003，用4 x 106 HeLa细胞的交联染色质以及20 µl Di-Methyl-Histone H3 (Lys9) (D85B4) XP® Rabbit mAb或2 µl Normal Rabbit IgG #2729进行染色质免疫沉淀实验。使用SimpleChIP® Human GAPDH Exon 1 Primers #5516、SimpleChIP® Human RPL30 Exon 3 Primers #7014、SimpleChIP® Human AFM Intron 1 Primers #5098和SimpleChIP® Human α Satellite Repeat Primers #4486，浓缩的DNA通过real-time PCR定量。在每个样品中免疫沉淀DNA的数量被当做一个相对于总input chromatin的数量的信号，相当于一。
