Flow Cytometry Assay for Recycling of LFA-1 in T-lymphocytes 流式细胞术检测T淋巴细胞中LFA-1的再循环 作者:Katarzyna Potrzebowska, Janne Lehtonen, Malin Samuelsson and Lena Svensson日期:12/05/2018,浏览量:101,Q&A: 0
To enable cells to move forward, cell surface integrins are internalized into an endosomal compartment and subsequently intracellularly transported to be re-exposed at a new site on the cell membrane. Leukocytes are the fastest migrating cell type in the human body, which express the leukocyte-specific integrin LFA-1. Here, we describe a flow ...

Integrin Dependent RhoB Activation Assay Using Leukocytes 白细胞内整合素依赖的RhoB激活实验 作者:Janne Lehtonen, Katarzyna Potrzebowska, Malin Samuelsson and Lena Svensson日期:12/05/2018,浏览量:58,Q&A: 0
To be able to migrate, leukocyte needs to re-use its adhesion molecules to move forward. These adhesion molecules are called integrins and are intracellularly transported via endocytosis and exocytosis in order to translocate to a new site on the cell membrane. The intracellular transportation is regulated by different small GTPases including ...

Ultrasound Guided Intra-thymic Injection to Track Recent Thymic Emigrants and Investigate T Cell Development 超声引导胸腺内注射并追踪新近胸腺迁出细胞和T细胞发育观测 作者:Haiguang Wang, David L. Owen, Lily J. Qian, Laura B. Chopp, Michael A. Farrar and Kristin A. Hogquist日期:12/05/2018,浏览量:94,Q&A: 0
To track recent thymic emigrants (RTEs) or study T cell development in the thymus, intra-thymic injection of a cellular tag or precursor cells for various T cell lineages is often desired. However, the traditional surgical approach to expose the thymus for intra-thymic injection is time-consuming and can cause a high level of pain and stress to ...

An in vitro Microscopy-based Assay for Microtubule-binding and Microtubule-crosslinking by Budding Yeast Microtubule-associated Protein 利用芽殖酵母微管相关蛋白研究微管结合和微管交联的体外显微镜检测法 作者:Yili Zhu, Weimin Tan and Wei-Lih Lee日期:12/05/2018,浏览量:212,Q&A: 0
In this protocol, we describe a simple microscopy-based method to assess the interaction of a microtubule-associated protein (MAP) with microtubules. The interaction between MAP and microtubules is typically assessed by a co-sedimentation assay, which measures the amount of MAP that co-pellets with microtubules by centrifugation, followed by ...

Genome-wide Estimation of Evolutionary Distance and Phylogenetic Analysis of Homologous Genes 进化距离的全基因组评估和同源基因的系统进化分析 作者:Meixia Zhao, Biao Zhang, Jianxin Ma and Damon Lisch日期:12/05/2018,浏览量:123,Q&A: 0
Homologous genes, including paralogs and orthologs, are genes that share sequence homologies within or between different species. Homologous genes originate from a common origin through speciation, genetic duplication or horizontal gene transfer. Estimation of the sequence divergence of homologous genes help us to understand divergence time, which ...

Using Arabidopsis Mesophyll Protoplasts to Study Unfolded Protein Response Signaling 利用拟南芥叶肉细胞原生质体研究未折叠蛋白响应信号 作者:Yan Bao and Diane C. Bassham日期:12/05/2018,浏览量:154,Q&A: 0
Various environmental stresses or artificial reagents can trigger unfolded protein accumulation in the endoplasmic reticulum (ER) due to the folding capacity of the ER being exceeded. This is termed ER stress, and triggers the unfolded protein response (UPR). Assays for activation of the UPR in plants include Tunicamycin (Tm)- or dithiothreitol ...

Wheat Germ Agglutinin (WGA)-SDS-PAGE: A Novel Method for the Detection of O-GlcNAc-modified Proteins by Lectin Affinity Gel Electrophoresis 小麦种子凝集素(WGA)-SDS-PAGE:一种利用凝集素亲和凝胶电泳对O-乙酰氨基葡萄糖修饰蛋白进行检测的新方法 作者:Ko Fujioka, Yuji Kubota and Mutsuhiro Takekawa日期:12/05/2018,浏览量:112,Q&A: 0
Diverse cytoplasmic and nuclear proteins dynamically change their molecular functions by O-linked β-N-acetylglucosamine (O-GlcNAc) modification on serine and/or threonine residues. Evaluation of the O-GlcNAcylation level of a specific protein, however, needs multiple and time-consuming steps if using conventional methods (e.g., ...
