Lipid mixing (redistribution of lipid probes between fusing membranes) has been widely used to study early stages of relatively fast viral and intracellular fusion processes that take seconds to minutes. Lipid mixing assays are especially important for identification of hemifusion intermediates operationally defined as lipid mixing without content ...

Zebrafish Bacterial Infection Assay to Study Host-Pathogen Interactions 斑马鱼细菌感染检测用于研究宿主-病原相互作用 作者:Faiza Basheer, Clifford Liongue and Alister C Ward日期:03/05/2020,浏览量:1307,Q&A: 0
The study of host-pathogen interactions has improved our understanding of both pathogenesis and the response of the host to infection, including both innate and adaptive responses. Neutrophils and macrophages represent the first line of innate host defense against any infection. The zebrafish is an ideal model to study the response of these cells ...

Optogenetic Tuning of Ligand Binding to The Human T cell Receptor Using The opto-ligand-TCR System 利用光配体TCR系统调节配体与人T细胞受体的结合 作者:O. Sascha Yousefi, Maximilian Hörner, Maximilian Wess, Vincent Idstein, Wilfried Weber and Wolfgang W. A. Schamel日期:03/05/2020,浏览量:1557,Q&A: 0
T cells are one major cell type of the immune system that use their T cell antigen receptor (TCR) to bind and respond to foreign molecules derived from pathogens. The ligand-TCR interaction half-lives determine stimulation outcome. Until recently, scientists relied on mutating either the TCR or its ligands to investigate how varying TCR-ligand ...

Growth Recovery Assay and FACS-based Population Sorting Following Territorial Exclusion in Proteus mirabilis 奇异变形杆菌被领土排斥后生长恢复测定和基于FACS的群体分类 作者:Murray J. Tipping and Karine A. Gibbs日期:03/05/2020,浏览量:1370,Q&A: 0
Many bacteria take part in self recognition and kin discrimination behavior using contact-dependent effectors. Understanding the effects these effectors cause is important to explain bacterial community formation and population dynamics. Typically, kin discrimination effectors are toxins that kill target cells; their effect is therefore obvious ...

Contemporaneous Measurement of Outer and Inner Membrane Permeability in Gram-negative Bacteria 革兰阴性菌中内外膜通透性的同期测定 作者:Bo Ma, Chao Fang, Jing Zhang, Mingzhi Wang, Xiaoxing Luo and Zheng Hou日期:03/05/2020,浏览量:1278,Q&A: 0
The emergence and rapid spread of multidrug resistance in bacteria have led to the urgent need for novel antibacterial agents. Membrane permeabilization is the mechanism for many antibacterial molecules that are being developed against gram-negative bacteria. Thus, to determine the efficacy of a potential antibacterial molecule, it is important to ...

Cell-free Reconstitution of the Packaging of Cargo Proteins into Vesicles at the trans Golgi Network 反面高尔基体网状结构中货物蛋白包装成囊泡的无细胞重组 作者:Xiao Tang, Feng Yang and Yusong Guo日期:03/05/2020,浏览量:1331,Q&A: 0
Protein sorting at the trans Golgi network (TGN) plays important roles in targeting newly synthesized proteins to their specific destinations. The aim of this proposal is to reconstitute the packaging of non-Golgi resident cargo proteins into vesicles at the TGN, utilizing rat liver cytosol, semi-intact mammalian cells and nucleotides. ...

Delayed Alternation Task for the Study of Spatial Working and Long Term Memory in Rats 延迟交替任务用于研究大鼠空间工作记忆和长期记忆 作者:Megi Hoxha and Marta Sabariego日期:03/05/2020,浏览量:1559,Q&A: 0
Memory systems can hold previously presented information for several seconds, bridging gaps between discontinuous events. It has been previously demonstrated that the hippocampus and the medial entorhinal cortex (mEC) are necessary for memory retention over delay intervals in alternation tasks. Here we describe the delayed alternation task, a ...

Autophagy is the main catabolic process in eukaryotes and plays a key role in cell homeostasis. In vivo measurement of autophagic activity (flux) is a powerful tool for investigating the role of the pathway in organism development and stress responses. Here we describe a significant optimization of the tandem tag assay for detection of ...
