Preparation of Sequencing RNA Libraries through Chemical Cross-linking Coupled to Affinity Purification (cCLAP) in Saccharomyces cerevisiae 通过化学交联联合亲和纯化(cCLAP) 技术制备酿酒酵母RNA测序文库 作者:Congwei Wang, Julie Weidner and Anne Spang日期:10/05/2018,浏览量:4378,Q&A: 0
Ribonucleoprotein particles (mRNPs) are complexes consisting of mRNAs and RNA-binding proteins (RBPs) which control mRNA transcription localization, turnover, and translation. Some mRNAs within the mRNPs have been shown to undergo degradation or storage. Those transcripts can lack general mRNA elements, like the poly(A) tail or 5’ cap structure, ...

A Method for SUMO Modification of Proteins in vitro 体外蛋白SUMO化修饰的方法 作者:Christine C. Lee, Bing Li, Hongtao Yu and Michael J. Matunis日期:10/05/2018,浏览量:4532,Q&A: 0
The Small Ubiquitin-related Modifier (SUMO) is a protein that is post-translationally added to and reversibly removed from other proteins in eukaryotic cells. SUMO and enzymes of the SUMO pathway are well conserved from yeast to humans and SUMO modification regulates a variety of essential cellular processes including transcription, chromatin ...

Filter Retardation Assay for Detecting and Quantifying Polyglutamine Aggregates Using Caenorhabditis elegans Lysates 使用秀丽隐杆线虫裂解液检测和定量聚谷氨酰胺聚集体的滤器延迟试验 作者:Olga Sin, Alejandro Mata-Cabana, Renée I. Seinstra and Ellen A. A. Nollen日期:10/05/2018,浏览量:5954,Q&A: 0
Protein aggregation is a hallmark of several neurodegenerative diseases and is associated with impaired protein homeostasis. This imbalance is caused by the loss of the protein’s native conformation, which ultimately results in its aggregation or abnormal localization within the cell. Using a C. elegans model of polyglutamine diseases, we ...

Detection of Cell Death in Planarians 真涡虫细胞死亡的检测 作者:Nídia de Sousa and Teresa Adell日期:10/05/2018,浏览量:4525,Q&A: 0
Planarians are freshwater flatworms, well known for their ability to regenerate a complete organism from any piece of their body. Furthermore, planarians are constantly growing and degrowing throughout their lives, maintaining a functional and proportioned body. These properties rely on the presence of a population of adult stem cells and on the ...

Isolation and Culture of Mouse Lung ILC2s 小鼠肺ILC2s的分离和培养 作者:Pauline Schmitt, Anais Duval, Emilie Mirey, Jean-Philippe Girard and Corinne Cayrol日期:10/05/2018,浏览量:6087,Q&A: 0
Group 2 Innate Lymphoid Cells (ILC2) play an important role in immune responses at barrier surfaces, notably in the lung during airway allergic inflammation or asthma. Several studies have described methods to isolate ILC2s from wild-type naive mice, most of them using cell sorting to obtain a pure population. Here, we describe in detail, a ...

Fluorescence Titrations to Determine the Binding Affinity of Cyclic Nucleotides to SthK Ion Channels 荧光滴定法测定环核苷酸与SthK离子通道的结合亲和力 作者:Philipp A.M. Schmidpeter and Crina M. Nimigean日期:10/05/2018,浏览量:6434,Q&A: 0
The cyclic-nucleotide modulated ion channel family includes cyclic nucleotide-gated (CNG) and hyperpolarization-activated and cyclic nucleotide-modulated (HCN) channels, which play essential roles in visual and olfactory signaling and the heart pacemaking activity. Functionally, these channels have been extensively characterized by ...

Isolation of Chromatin-bound Proteins from Subcellular Fractions for Biochemical Analysis 从亚细胞成分中分离用于生化分析的染色质结合蛋白 作者:Sébastien Gillotin日期:10/05/2018,浏览量:13993,Q&A: 5
Shuttling of proteins between different cellular compartments controls their proteostasis and can contribute in some cases to regulate their activity. Biochemical analysis of chromatin-bound proteins, such as transcription factors, is often difficult because of their low yield and due to the interference from nucleic acids. This protocol describes ...
