30次 产品简介: 来源 用途 交叉反应性 抗体识别位点 Histone H3分子量 Rabbit WB, IF H Histone H3 N-terminal ~17kD WB, Western blot;

IF, Immunofluorescence. H, human. ? 本Histone H3抗体(Histone H3 antibody)为进口分装,用人工合成的人histone H3氨基端 aa 1-20该段多肽进行适当修饰后免疫 rabbit,然后用protein A和抗原多肽亲和柱经过两步纯化得到的高纯度抗体. ? 本Histone H3抗体识别的是总histone H3(total histone H3),可检测内源性的Histone H3,未发现和其它组蛋白有交叉反应. ? 组蛋白histone H2A, H2B,H3和H4各两个分子组成的八聚体和与该八聚体相结合的DNA构成了染色质的基本结构核小体 (necliosome).组蛋白的存在确保了基因组DNA可以被相对致密而有序地堆放在细胞核中.人一个细胞的基因组DNA完全拉 成线性的总长度约为1.4米, 但染色质的总长度仅为9厘米, 而有丝分裂时染色体的总长度仅为0.12毫米. 除了核心组蛋白(core histone) histone H2A, H2B,H3和H4外,还有一类linker histone H1和H5.Histone H1可以结合核小体和DNA在核小体中进 出的位点,从而使DNA的位置被锁定,有利于在核小体基础上形成更高级的空间结构(参考下图).组蛋白结合区域的DNA 长度为147bp,核小体间的DNA长度大约为50bp.染色质空间结构的松散还是致密很大程度上决定了该区域基因转录水平的 高低(参考下图). ? 组蛋白是真核生物中呈强碱性的蛋白.组蛋白可以被乙酰化、磷酸化、甲基化和泛素化修饰.这些修饰会改变染色质的空 间结构,从而在基因转录调控、染色体装配等过程中起重要作用.通常,histone H2B的Lys5,Lys12和Lys15会发生乙酰化修 饰.Histone H3的Lys9,Lys14,Lys18和Lys23会发生乙酰化修饰.Histone H3的Ser10,Ser28和Thr11都会发生磷酸化修饰. Histone H3的这些磷酸化和有丝分裂或减数分裂过程中的染色质浓缩密切相关.Histone H3 Thr3的磷酸化在很多物种中都非 常保守,可以被激酶haspin所催化.Histone H3的Thr3磷酸化发生在有丝分裂早期(prophase),在有丝分裂的晚期(anaphase) 则被去磷酸化.Histone H3和H4是甲基化修饰的主要组蛋白,哺乳动物细胞中histone H3和H4是高度甲基化的.组蛋白可以 被单、双或三甲基化(mono-, di-, and tri-methylated),和基因转录调控和染色体装配密切相关. ? Histone H3在其氨基端有一个较长的N terminal tail, 在核小体的装配过程中起关键作用. Histone H3是各种histone中修饰程度 最高的,在表观遗传(epigenetics)中起重要作用.Histone H3包括H3A

1、H3A2和H3A3.人的hitone H3由近15个基因分别单 独编码. ? 配套提供了Western一抗稀释液,可以用于Western检测时的一抗稀释. ? 建议抗体使用时的稀释比例如下(实际使用时需根据抗原水平的高低作适当调整): WB IF 1:1000 1:100
