Specificity / Sensitivity

Ezh2 Antibody detects endogenous levels of Ezh2 protein. The antibody may cross-react with Ezh2-related proteins.

Ezh2 Antibody检能够测内源性Ezh2总蛋白水平。该抗体可能与Ezh2相关的蛋白发生交叉反应。

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Arg354 of human Ezh2 protein. Antibodies are purified by protein A and peptide affinity chromatography.


Western Blotting

Western Blotting

Western blot analysis of extracts from various cell lines using Ezh2 Antibody.

使用Ezh2 Antibody,免疫印迹(Western blot)分析不同细胞系中Ezh2的蛋白水平。

Chromatin IP

Chromatin IP

Chromatin immunoprecipitations were performed with cross-linked chromatin from 4 x 106 NCCIT cells and either 20 µl of EZH2 Antibody 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 HoxA1 Intron 1 Primers #7707, SimpleChIP® Human HoxA2 Promoter Primers #5517 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 NCCIT细胞的交联染色质以及5 µl EZH2 Antibody或2 µl Normal Rabbit IgG #2729进行染色质免疫沉淀实验。使用SimpleChIP® Human HoxA1 Intron 1 Primers #7707、SimpleChIP® Human HoxA2 Promoter Primers #5517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,这相当于一。


The polycomb group (PcG) proteins are involved in maintaining the silenced state of several developmentally regulated genes and contribute to the maintenance of cell identity, cell cycle regulation, and oncogenesis (1,2). Enhancer of zeste homolog 2 (Ezh2), a member of this large protein family, contains four conserved regions including domain I, domain II, and a cysteine-rich amino acid stretch that precedes the carboxy-terminal SET domain (3). The SET domain has been linked with histone methyltransferase (HMTase) activity. Moreover, mammalian Ezh2 is a member of a histone deacetylase complex that functions in gene silencing, acting at the level of chromatin structure (4). Ezh2 complexes methylate histone H3 at Lys9 and 27 in vitro, which is thought to be involved in targeting transcriptional regulators to specific loci (5). Ezh2 is deregulated in various tumor types, and its role, both as a primary effector and as a mediator of tumorigenesis, has become a subject of increased interest (6).

polycomb group (PcG)蛋白是涉及维持数个发育调节基因的沉默水平,并且有助于维持细胞身份(cell identity)、细胞周期调节和肿瘤发生(1,2)。zeste homolog 2 (Ezh2)的增强子是一个该蛋白家族成员,它包含四种保守区域包括domain I、domain II、一个半胱氨酸富裕的氨基酸延伸序列和羧基端SET domain (3)。SET domain已经证明与histone methyltransferase (HMTase)活性有关联。此外,哺乳类Ezh2是一个组蛋白去乙酰酶复合物的成员之一,它在基因沉默中有功能,并且在染色质结构水平起着作用(4)。在体内,Ezh2复合物使histone H3在Lys9和27位点甲基化,这被认为是涉及到调节转录因子到特异的靶位点(5)。Ezh2蛋白在不同肿瘤形式中被下调,并且具有主要效应因子和肿瘤发生的调节因子的作用已经变成一个越来越感兴趣的课题(6)。
