In vitro Measurement of CMP-Sialic Acid Transporter Activity in Reconstituted Proteoliposomes 重组蛋白脂质体中CMP-唾液酸转运体活性的体外检测 作者:James Cahill, Shivani Ahuja and Matthew R. Whorton日期:03/20/2020,浏览量:206,Q&A: 0
Nucleotide-sugar transporters (NSTs) facilitate eukaryotic cellular glycosylation by transporting nucleotide-sugar conjugates into the Golgi lumen and endoplasmic reticulum for use by glycosyltransferases, while also transferring nucleotide monophosphate byproducts to the cytoplasm. Mutations in this family of proteins can cause a number of ...

Self-organization Assay for Min Proteins of Escherichia coli in Micro-droplets Covered with Lipids 脂质微滴中大肠杆菌Min蛋白的自组织分析 作者:Shunshi Kohyama, Kei Fujiwara, Natsuhiko Yoshinaga and Nobuhide Doi日期:03/20/2020,浏览量:165,Q&A: 0
The Min system determines the cell division plane of bacteria. As a cue of spatiotemporal regulation, the Min system uses wave propagation of MinD protein (Min wave). Therefore, the reconstitution of the Min wave in cell-sized closed space will lead to the creation of artificial cells capable of cell division. The Min waves emerge via coupling ...

Single-cell qPCR Assay with Massively Parallel Microfluidic System 大规模平行微流控系统用于单细胞qPCR检测 作者:Marta Prieto-Vila, Takahiro Ochiya and Yusuke Yamamoto日期:03/20/2020,浏览量:180,Q&A: 0
The single-cell transcriptome is the set of messenger RNA molecules expressed in one cell. It is extremely variable and changes according to external, physical and biochemical conditions. Due to sensitivity shortages, most of genetic studies use bulk samples, providing only the average gene expression. Single-cell technologies have provided a ...

Testing Bone Formation Induction by Calvarial Injection Assay in vivo 体内颅骨注射分析检测骨形成 作者:Narelle E McGregor, Ingrid J Poulton, Emma C Walker and Natalie A Sims日期:03/20/2020,浏览量:257,Q&A: 0
Bone formation occurs during embryogenesis, skeletal growth and during the process of skeletal renewal throughout life. In the process of bone formation, osteoblasts lay down a collagen-containing matrix, termed osteoid, which is gradually hardened by incorporation of mineral crystals. Although osteoblasts can be induced to differentiate and to ...

Accelerated Snowmelt Protocol to Simulate Climate Change Induced Impacts on Snowpack Dependent Ecosystems 加速雪融诱发气候变化对依赖雪被斑块生态系统的影响 作者:Laura T. Leonard, Chelsea Wilmer, Heidi Steltzer, Kenneth H. Williams and Jonathan O. Sharp日期:03/20/2020,浏览量:292,Q&A: 0
Field studies that simulate the effects of climate change are important for a predictive understanding of ecosystem responses to a changing environment. Among many concerns, regional warming can result in advanced timing of spring snowmelt in snowpack dependent ecosystems, which could lead to longer snow-free periods and drier summer soils. Past ...

Analyzing the Quenchable Iron Pool in Murine Macrophages by Flow Cytometry 小鼠巨噬细胞可淬灭铁池的流式细胞分析 作者:Michael Riedelberger and Karl Kuchler日期:03/20/2020,浏览量:127,Q&A: 0
Tissue-resident macrophages are pivotal for a tightly-regulated iron metabolism at a cellular and systemic level, since subtle iron alterations increase the susceptibility for microbial infections or drive multiple diseases. However, research on cellular iron homeostasis in macrophages remains challenging due to the limited amount of available ...

Method for Measuring Mucociliary Clearance and Cilia-generated Flow in Mice by ex vivo Imaging 小鼠中黏膜纤毛清除和纤毛产生流动的离体成像检测方法 作者:Eric Song and Akiko Iwasaki日期:03/20/2020,浏览量:179,Q&A: 0
Ex vivo biophysical measurements provide valuable insights into understanding both physiological and pathogenic processes. One critical physiological mechanism that is regulated by these biophysical properties is cilia-generated flow that mediates mucociliary clearance, which is known to provide protection against foreign particles and ...

Characterization of Immunological Niches within Peyer’s Patches by ex vivo Photoactivation and Flow Cytometry Analysis 体外光激活和流式细胞术分析派尔斑免疫龛位 作者:Adi Biram and Ziv Shulman日期:03/20/2020,浏览量:196,Q&A: 0
T follicular helper (Tfh) cells regulate B cell selection for entry into the germinal center (GC) reaction or for differentiation into antibody forming cells. This process takes place at the border between the T and B zones in lymphoid organs and involves physical contacts between T and B cells. During these interactions, T cells endow the B cells ...

Purification of Rice Stripe Virus 水稻条纹病毒纯化 作者:Gang Lu, Min Yao, Yijun Zhou and Xiaorong Tao日期:03/20/2020,浏览量:126,Q&A: 0
Although many spherical and rod-shaped plant virus purification protocols are now available, only a few protocols on filamentous plant virus purification have been published. Here, we report a protocol for large-scale purification of Rice stripe virus (RSV) from RSV-infected rice tissues. RSV virions with high infectivity were first precipitated ...

High-resolution and Deep Phylogenetic Reconstruction of Ancestral States from Large Transcriptomic Data Sets 从大型转录组数据集中进行原始状态的高通量深度系统发育重建 作者:Sumanth Kumar Mutte and Dolf Weijers日期:03/20/2020,浏览量:251,Q&A: 0
Phylogenetics is an important area of evolutionary biology that helps to understand the origin and divergence of genes, genomes and species. Building meaningful phylogenetic trees is needed for the accurate reconstruction of the past. To achieve a correct phylogenetic understanding of genes or proteins, reliable and robust methods are needed to ...

An ex vivo Approach to Assess Mitochondrial ROS by Flow Cytometry in AAV-tagged Astrocytes in Adult Mice 一种利用流式细胞术进行成年大鼠腺相关病毒标记星型胶质细胞中线粒体ROS水平的体外检测方法 作者:Carlos Vicente-Gutierrez and Juan P. Bolaños日期:03/20/2020,浏览量:388,Q&A: 0
Mitochondrial reactive oxygen species (mROS) are naturally produced signalling molecules extremely relevant for understanding both health- and disease-associated biological processes. The study of mROS in the brain is currently underway to decipher their physiopathological roles and contributions in neurological diseases. Recent advances in this ...

Phototactic T-maze Behavioral Assay for Comparing the Functionality of Color-sensitive Photoreceptor Subtypes in the Drosophila Visual System 趋光T-迷宫行为分析用于果蝇视觉系统中色彩敏感光感应器亚型的比较 作者:Hunter S. Shaw, Joe Larkin and Yong Rao日期:03/20/2020,浏览量:111,Q&A: 0
The Drosophila retina contains light-sensitive photoreceptors (R cells) with distinct spectral sensitivities that allow them to distinguish light by its spectral composition. R7 and R8 photoreceptors are important for color vision, and can be further classified into pale (p) or yellow (y) subtypes depending on the rhodopsin expressed. ...

Optic Nerve Crush in Mice to Study Retinal Ganglion Cell Survival and Regeneration 视神经挤压对小鼠视网膜神经节细胞存活和再生的影响 作者:Evan G. Cameron, Xin Xia, Joana Galvao, Masoumeh Ashouri, Michael S. Kapiloff and Jeffrey L. Goldberg日期:03/20/2020,浏览量:170,Q&A: 0
In diseases such as glaucoma, the failure of retinal ganglion cell (RGC) neurons to survive or regenerate their optic nerve axons underlies partial and, in some cases, complete vision loss. Optic nerve crush (ONC) serves as a useful model not only of traumatic optic neuropathy but also of glaucomatous injury, as it similarly induces RGC cell death ...

Shared Pheromonal Communication of Specific Fear Between Adult Sprague Dawley Rats 成年SD大鼠特定恐惧的信息素通讯 作者:Samantha J. Carew and Abhinaba Ghosh日期:03/20/2020,浏览量:146,Q&A: 0
Rats are highly social animals, and mainly communicate with one another in two ways: through ultrasonic vocalizations and pheromones. Most research on pheromones has been dedicated those regarding sexual behavior, but more recently pheromones which signal danger to conspecifics have been identified in rodents. In fact, rats are capable of ...
