    [Abstract]

    Experimental results in fungal biology research are usually obtained as average measurements across whole populations of cells, whilst ignoring what is happening at the single cell level. Microscopy has allowed us to study single-cell behavior, but it has low throughput and cannot be used to select individual cells for downstream experiments. Here

    Generation and Implementation of Reporter BHK-21 Cells for Live Imaging of Flavivirus Infection
    黄病毒感染活体显像报告细胞BHK-21的制备与实施

    [Abstract]

    The genus Flavivirus within the family Flaviviridae includes many viral species of medical importance, such as yellow fever virus (YFV), Zika virus (ZIKV), and dengue virus (DENV), among others. Presently, the identification of flavivirus-infected cells is based on either the immunolabeling of viral proteins, the application of recombinant

    Analysis of Gram-negative Bacteria Peptidoglycan by Ultra-performance Liquid Chromatography
    革兰阴性菌肽聚糖的超高效液相色谱法分析
    作者:Laura Alvarez, Baptiste Cordier, Sven van Teeffelen and Felipe Cava日期:10/05/2020,浏览量:1992,Q&A: 0
    [Abstract] Bacteria are surrounded by a protective peptidoglycan cell wall. Provided that this structure and the enzymes involved are the preferred target for our most successful antibiotics, determining its structural and chemical complexity is of the highest interest. Traditionally, high-performance liquid chromatography (HPLC) analyses have been ...
    In vitro Cultivation and Visualization of Malaria Liver Stages in Primary Simian Hepatocytes
    猴原代肝细胞体外培养及疟疾肝期观察
    作者:Devendra Kumar Gupta and Thierry Diagana日期:08/20/2020,浏览量:2061,Q&A: 0
    [Abstract] Human liver is the primary and obligatory site for malaria infection where sporozoites invade host hepatocytes. Malaria hepatic stages are asymptomatic and represent an attractive target for development of anti-malarial interventions and vaccines. However, owing to lack of robust and reproducible in vitro culture system, it is difficult ...
    Live Cell Measurement of the Intracellular pH of Yeast by Flow Cytometry Using a Genetically-Encoded Fluorescent Reporter
    一种基于流式细胞术的利用基因编码荧光报告测定酵母活细胞内pH值的方法
    作者:Catherine G. Triandafillou and D. Allan Drummond日期:06/20/2020,浏览量:2171,Q&A: 0
    [Abstract] The intracellular pH of yeast is a tightly regulated physiological cue that changes in response to growth state and environmental conditions. Fluorescent reporters, which have altered fluorescence in response to local pH changes, can be used to measure intracellular pH. While microscopy is often used to make such measurements, it is relatively ...
    TZA, a Sensitive Reporter Cell-based Assay to Accurately and Rapidly Quantify Inducible, Replication-competent Latent HIV-1 from Resting CD4+ T Cells
    TZA, 一种基于敏感报告因子细胞学检测方法, 可用于准确快速量化静息CD4+ T细胞中可诱导的且复制能力强的潜伏HV-1
    作者:Anwesha Sanyal, Vatsala S. Rangachar and Phalguni Gupta日期:05/20/2019,浏览量:5026,Q&A: 1
    [Abstract] The latent HIV-1 viral reservoir in resting CD4+ (rCD4+) T cells represents a major barrier to an HIV-1 cure. There is an ongoing effort to identify therapeutic approaches that will eliminate or reduce the size of this reservoir. However, clinical investigators lack an assay to determine whether or not a decrease in the ...
    Analysis of Early Phase HIV-1 Replication and Integration Events by Using Real-time PCR
    利用实时PCR对早期HIV-1复制和整合过程进行检测
    作者:Graf Laura, Steven P. Moran, Sally Ro, Carlos M.C. de Noronha and Binshan Shi日期:02/20/2019,浏览量:3838,Q&A: 0
    [Abstract] Upon entry into a host cell, the HIV-1 virus undergoes a series of critical early replication events including reverse transcription, nuclear import, and integration of its cDNA into the host genome. Molecular assays used to detect and analyze changes in HIV-1 early phase replication events are valuable tools in developing potential antiretroviral ...
    In vivo Analysis of Cyclic di-GMP Cyclase and Phosphodiesterase Activity in Escherichia coli Using a Vc2 Riboswitch-based Assay
    使用基于Vc2 Riboswitch的测定法体内分析大肠杆菌中环状di-GMP环化酶和磷酸二酯酶活性
    作者:Ying Liu, Hyunhee Kim and Ute Römling日期:03/05/2018,浏览量:5500,Q&A: 0
    [Abstract] Cyclic di-guanosine monophosphate (c-di-GMP) is a ubiquitous second messenger that regulates distinct aspects of bacterial physiology. It is synthesized by diguanylate cyclases (DGCs) and hydrolyzed by phosphodiesterases (PDEs). To date, the activities of DGC and PDE are commonly assessed by phenotypic assays, mass spectrometry analysis of ...
    Isolation, BODIPY Labeling and Uptake of Exosomes in Hepatic Stellate Cells
    肝星状细胞中外泌体的分离、BODIPY标记和摄取
    作者:Shubham Shrivastava日期:12/05/2017,浏览量:8802,Q&A: 1
    [Abstract] Exosomes have emerged as an important mediator of intercellular communication. They are present in extracellular milieu and therefore, easily accessible by neighboring or distant cells. They carry mRNA, microRNAs and proteins within their vesicles and once internalized by recipient cells; they can modulate multiple signaling pathways with ...
    Serial Immunoprecipitation of 3xFLAG/V5-tagged Yeast Proteins to Identify Specific Interactions with Chaperone Proteins
    连续免疫沉淀3xFLAG/V5标记的酵母蛋白以鉴定特异性互作伴侣蛋白
    作者:Xu Zheng and David Pincus日期:06/20/2017,浏览量:7031,Q&A: 0
    [Abstract] This method was generated to isolate high affinity protein complexes from yeast lysate by performing serial affinity purification of doubly tagged 3xFLAG/V5 proteins. First, the bait protein of interest is immunoprecipitated by anti-FLAG-conjugated magnetic beads and gently eluted by 3xFLAG antigen peptide. Next, the bait protein is recaptured ...
