抗拓扑异构酶II(p170)抗体。这是一种针对p170的C末端区域的兔源抗体(多克隆)。使用肽段来诱导产生这种抗血清;抗体已经过免疫亲和纯化。试剂盒包含100微升的抗体。
肽段试剂。包含总共50微克(2毫克/毫升)的肽段。该序列是p170的C末端16个氨基酸残基。此肽段位于磷酸钠缓冲液中。
详细操作手册。该协议是为使用贴壁细胞培养(HeLa、Vero、3T3等)开发的。涉及悬浮细胞培养、薄片或辣根过氧化物酶染色的应用将需要研究者自行调整。需要注意的是,由于拓扑异构酶II在染色体中高度富集,方法内建了内部对照;在有丝分裂细胞中,您应该能看到明亮的荧光染色体。
将此试剂盒储存在-20°C。
人拓扑异构酶I电泳迁移率变化分析试剂盒文献参考:
As noted above topoisomerase II has a characteristic distribution pattern in cells that clearly indicates whether the procedure is working. In interphase cells, the pattern of distribution of topo II is almost totally nuclear and appears to be punctiform or pin-point in nature. The signal is clearly amplified in metaphase cells when chromosomes are visible. There should be about a 5-10 fold increase in fluorescent intensity in the latter cells.
The peptide that is included is an important control reagent. Incubating the cells with peptide plus primary topo II antibody should neutralize the fluorescent signal.
