    A Flow Cytometry-Based Method for Analyzing DNA End Resection in G0- and G1-Phase Mammalian Cells
    一种基于流式细胞术的分析 G0和G1期哺乳动物细胞中 DNA 末端切除的方法

    [Abstract]

    DNA double strand breaks (DSBs) constantly arise in cells during normal cellular processes or upon exposure to genotoxic agents, and are repaired mostly by homologous recombination (HR) and non-homologous end joining (NHEJ). One key determinant of DNA DSB repair pathway choice is the processing of broken DNA ends to generate single strand DNA

    Flow Cytometry-based Measurement of Reactive Oxygen Species in Cyanobacteria
    基于流式细胞仪的蓝藻活性氧测量

    [Abstract]

    Cyanobacteria are Gram-negative oxygen-producing photosynthetic bacteria that are useful in the pharmaceutical and biofuel industries. Monitoring of oxidative stress under fluctuating environmental conditions is important for determining the fitness, survival, and growth of cyanobacteria in the laboratory as well as in large scale cultivation

    Small Molecule Screening of Primary Human Acute Myeloid Leukemia Using Co-culture and Multiplexed FACS Analysis
    使用共培养和多重 FACS 分析对原发性人类急性髓细胞白血病进行小分子筛选

    [Abstract]

    Ex vivo culture of primary acute myeloid leukemia (AML) cells is notoriously difficult due to spontaneous differentiation and cell death, which hinders mechanistic and translational studies. To overcome this bottleneck, we have implemented a co-culture system, where the OP9-M2 stromal cells support the growth, but most notably limit the

    [Abstract]

    All eukaryotic cells are equipped with transmembrane lipid transporters, which are key players in membrane lipid asymmetry, vesicular trafficking, and membrane fusion. The link between mutations in these transporters and disease in humans highlights their essential role in cell homeostasis. Yet, many key features of their activities, their

    Flow Cytometry Analysis of Planarian Stem Cells Using DNA and Mitochondrial Dyes
    利用DNA和线粒体染料流式细胞术分析涡虫干细胞

    [Abstract]

    Planarians are free-living flatworms that emerged as a crucial model system to understand regeneration and stem cell biology. The ability to purify neoblasts, the adult stem cell population of planaria, through fluorescence-activated cell sorting (FACS) has tremendously increased our understanding of pluripotency, specialization, and

    Evaluating Human Natural Killer Cells Antibody-dependent Cellular Cytotoxicity (ADCC) Using Plate-bound Anti-CD16 Antibodies
    使用板结合抗 CD16 抗体评估人类自然杀伤细胞抗体依赖性细胞毒性 (ADCC)
    作者:Weiru Liu日期:01/05/2022,浏览量:1497,Q&A: 0
    [Abstract]

    Natural killer (NK) cells are large granular lymphocytes that keep in check the health of neighboring cells through a large array of intrinsically expressed germline-coded receptors. Most importantly, CD16 is a low affinity Fc receptor for IgG that mediates the antibody-dependent cellular cytotoxicity (ADCC) of NK cells, bridging the innate and

    Suppression of Human Dendritic Cells by Regulatory T Cells

    [Abstract]

    Regulatory T cells (Tregs) suppress immune responses via a variety of mechanisms and can be used as a cellular therapy to induce tolerance. The function of Tregs is commonly assessed in vitro using assays that measure suppression of effector T cell proliferation and/or cytokine production. However, Tregs can also suppress the function of antigen

    Plasmodium cynomolgi Berok Growth Inhibition Assay by Thiol-reactive Probe Based Flow Cytometric Measurement

    [Abstract]

    The relapsing malaria species, Plasmodium vivax, is the most widely distributed and difficult-to-treat cause of human malaria. The merozoites of P. vivax preferentially invade ephemeral human CD71+ reticulocytes (nascent reticulocytes), thereby limiting the development of a robust continuous culture in vitro. Fortunately, P. vivax’s sister

    One-step White Blood Cell Extracellular Staining Method for Flow Cytometry

    [Abstract]

    Flow cytometry is a powerful analytical technique that is increasingly used in scientific investigations and healthcare; however, it requires time-consuming, multi-step sample procedures, which limits its use to specialized laboratories. In this study, we propose a new universal one-step method in which white blood cell staining and red blood cell

    Isolation of Microglia and Analysis of Protein Expression by Flow Cytometry: Avoiding the Pitfall of Microglia Background Autofluorescence
    小胶质细胞的分离及蛋白表达的流式细胞仪分析:避免小胶质细胞背景荧光的陷阱

    [Abstract]

    Microglia are a unique type of tissue-resident innate immune cell found within the brain, spinal cord, and retina. In the healthy nervous system, their main functions are to defend the tissue against infectious microbes, support neuronal networks through synapse remodeling, and clear extracellular debris and dying cells through phagocytosis. Many
