Rapid Profiling Cell Cycle by Flow Cytometry Using Concurrent Staining of DNA and Mitotic Markers

[Abstract]  The flow cytometric quantitation of DNA content by DNA-binding fluorochrome, propidium iodide (PI) is the most widely used method for cell cycle analysis. However, the commonly used methods are time-consuming and labor-intensive and are incompatible with staining of mitotic markers by fluorescent-labeled antibodies. Here, we report an optimized simple protocol for rapid and simultaneous analysis of characteristic mitotic phosphorylated proteins and DNA content, permitting the quantification of cells in mitosis, G1, S and G2 stage in a single assay. The protocol detailed here employs detergent-based hypotonic solution to rapidly permeabilize cells and allows simultaneous staining of DNA with PI and mitotic marker, phospho-Histone H3, with specific antibody within 20 ... [摘要]  DNA结合荧光染料,碘化丙啶(PI)对DNA含量的流式细胞定量是细胞周期分析中使用最广泛的方法。 然而,常用的方法是耗时且劳动密集的,并且与通过荧光标记的抗体对有丝分裂标记物的染色不相容。 在这里,我们报告了一个优化的简单方案,用于快速和同时分析特征有丝分裂磷酸化蛋白和DNA含量,允许在单次测定中有丝分裂,G1,S和G2期细胞的定量。 这里详述的方案采用基于洗涤剂的低渗溶液来快速透化细胞,并允许在20分钟内同时用PI和有丝分裂标记物磷酸组蛋白H3与特异性抗体染色DNA。 该方案仅需要廉价和商业可用的试剂,并且还能够快速和完整地分析细胞周期特征。
【背景】通过流式细胞术进行细胞周期分析主要基于用碘化丙啶(PI)染色测量DNA含量。 PI的化学计量特性确保DNA含量的准确定量,并且允许我们揭示G1,S和G2细胞周期阶段或G1期细胞死亡期细胞的分布,后者以DNA片段化为特征。用于基于PI的DNA定量的大多数常用方法需要使用酒精或醛固色,这是耗时且劳动密集型的。此外,这些方法与通过荧光标记的抗体对有丝分裂标记物的染色不相容。因此,我们采用和优化了以前建立的低渗缓冲液以使细胞透化,允许用PI和有丝分裂标记物磷酸组蛋白H3(pH3)同时染色DNA与pH3特异性抗体(Riccardi等人,2006; Liu et al。 ...

[Abstract]  Eosinophils are multifunctional effector cells implicated in the pathogenesis of a variety of diseases including asthma, eosinophil gastrointestinal disorders and helminth infection. Mouse bone marrow derived progenitor cells can be differentiated into eosinophils following IL-5 exposure. These bone marrow derived eosinophils are fully differentiated at the end of a 14 day culture based on morphology and expression of molecular markers.
[摘要]  嗜酸性粒细胞是涉及多种疾病的发病机理的多功能效应细胞,包括哮喘,嗜酸性粒细胞胃肠道疾病和蠕虫感染。 小鼠骨髓来源的祖细胞可以在IL-5暴露后分化成嗜酸性粒细胞。 这些骨髓衍生的嗜酸性粒细胞在14天培养结束时基于分子标志物的形态学和表达完全分化。
