Click-iT EdU 细胞增殖成像试剂盒是一种优于传统细胞增殖检测的替代方法,其针对荧光显微镜应用进行了优化。在该检测中,将经修饰的胸苷类似物 EdU 有效地掺入新合成的 DNA 中,并在快速、高度特异性的 click 反应中用明亮的、光稳定的 Alexa Fluor™ 染料进行荧光标记。得益于温和的 click 方案,这种增殖细胞的荧光标记非常准确并且与抗体方法兼容。
•简单—每次都能在更短的时间内完成工作 • 高效—无需变性步骤或严苛处理 • 丰富的检测结果—更好地保存细胞形态、抗原结构和 DNA 完整性 • 一致—不依赖于可变的抗体批次进行检测
准确的细胞增殖检测方法是基于核苷类似物在新合成 DNA 中的掺入及测量,其中溴脱氧尿苷 (BrdU) 是一种常用的类似物。通过严苛处理方法(HCl、加热或酶)使 DNA 变性并暴露于 BrdU 分子后,使用抗 BrdU 抗体对 BrdU 标记的 DNA 进行定量检测。此步骤耗时且难以一致地执行。严苛处理也会对样品的完整性和质量产生不利影响,这使得与其他抗体的共染色具有挑战性。
卓越的增殖方法学 Click-iT EdU 细胞增殖成像试剂盒可提供一种优于 BrdU 检测的细胞增殖检测方法。EdU(5-乙基-2'-脱氧尿苷)是脱氧胸腺嘧啶的核苷类似物,在活跃的 DNA 合成过程中掺入 DNA 中。使用 Click-iT™ EdU,温和的固定和洗涤剂透化足以使基于小分子的 Click-iT™ EdU 检测试剂获得掺入 DNA 的路径。因此,Click-iT™ EdU 成像试剂盒不仅简便易用,而且更准确且与细胞周期分析以及其他的细胞内或细胞外目标成分相兼容,以获得令人满意且丰富的检测结果。
BRCA1-associated exclusion of 53BP1 from DNA damage sites underlies temporal control of DNA repair.
Authors:Chapman JR, Sossick AJ, Boulton SJ, Jackson SP,
Journal:J Cell Sci
PubMed ID:22553214
'Following irradiation, numerous DNA-damage-responsive proteins rapidly redistribute into microscopically visible subnuclear aggregates, termed ionising-radiation-induced foci (IRIF). How the enrichment of proteins on damaged chromatin actually relates to DNA repair remains unclear. Here, we use super-resolution microscopy to examine the spatial distribution of BRCA1 and 53BP1 proteins within single IRIF at ... More
Quiescent gastric stem cells maintain the adult Drosophila stomach.
Authors:Strand M, Micchelli CA,
Journal:Proc Natl Acad Sci U S A
PubMed ID:21984734
'The adult Drosophila copper cell region or "stomach" is a highly acidic compartment of the midgut with pH < 3. In this region, a specialized group of acid-secreting cells similar to mammalian gastric parietal cells has been identified by a unique ultrastructure and by copper-metallothionein fluorescence. However, the homeostatic mechanism ... More
Long-term live imaging provides new insight into stem cell regulation and germline-soma coordination in the Drosophila ovary.
Authors:Morris LX, Spradling AC,
Journal:Development
PubMed ID:21558370
'The Drosophila ovariole tip produces new ovarian follicles on a 12-hour cycle by controlling niche-based germline and follicle stem cell divisions and nurturing their developing daughters. Static images provide a thumbnail view of folliculogenesis but imperfectly capture the dynamic cellular interactions that underlie follicle production. We describe a live-imaging culture ... More
Histone H3 lysine 4 methylation marks postreplicative human cytomegalovirus chromatin.
Authors:Nitzsche A, Steinhäusser C, Mücke K, Paulus C, Nevels M,
Journal:J Virol
PubMed ID:22761369
'In the nuclei of permissive cells, human cytomegalovirus genomes form nucleosomal structures initially resembling heterochromatin but gradually switching to a euchromatin-like state. This switch is characterized by a decrease in histone H3 K9 methylation and a marked increase in H3 tail acetylation and H3 K4 methylation across the viral genome. ... More
Schwann cell myelination requires integration of laminin activities.
'Laminins promote early stages of peripheral nerve myelination by assembling basement membranes (BMs) on Schwann cell surfaces, leading to activation of ß1 integrins and other receptors. The BM composition, structural bonds and ligands needed to mediate this process, however, are not well understood. Mice hypomorphic for laminin ?1-subunit expression that ... More
