Photoactivable Cholesterol as a Tool to Study Interaction of Influenza Virus Hemagglutinin with Cholesterol 利用光活化胆固醇研究流感病毒血凝素与胆固醇相互作用 作者:Bodan Hu, Mohamed Rasheed Gadalla, Christoph Thiele and Michael Veit日期:02/20/2020,浏览量:704,Q&A: 0
Non-covalent binding of cholesterol to the transmembrane region of proteins affect their functionalities, but methods to prove such an interaction are rare. We describe our protocol to label the hemagglutinin (HA) of Influenza virus with a cholesterol derivative in living cells or with immunoprecipitated protein. We synthesized a “clickable” ...

RNA Sequencing of Single Myofibers from Mus musculus 小鼠单肌纤维的RNA序列分析 作者:Darren M. Blackburn, Felicia Lazure and Vahab D. Soleimani日期:02/20/2020,浏览量:1369,Q&A: 0
Whole transcriptome analysis is a key method in biology that allows researchers to determine the effect a condition has on gene regulation. One difficulty in RNA sequencing of muscle is that traditional methods are performed on the whole muscle, but this captures non-myogenic cells that are part of the muscle. In order to analyze only the ...

Super-resolution Microscopy-based Bimolecular Fluorescence Complementation to Study Protein Complex Assembly and Co-localization 基于高分辨率显微镜的双分子荧光互补用于蛋白复合体装配和共定位 作者:Jingjing Chen, Zulin Yu, Jay R. Unruh, Brian D. Slaughter and Sue L. Jaspersen日期:02/20/2020,浏览量:1047,Q&A: 0
Numerous experimental approaches exist to study interactions between two subunits of a large macromolecular complex. However, most methods do not provide spatial and temporal information about binding, which are critical for dissecting the mechanism of assembly of nanosized complexes in vivo. While recent advances in super-resolution ...

Assessing Self-interaction of Mammalian Nuclear Proteins by Co-immunoprecipitation 共免疫沉淀法评价哺乳动物核蛋白的自身相互作用 作者:Claudia Cattoglio, Iryna Pustova, Xavier Darzacq, Robert Tjian and Anders S. Hansen日期:02/20/2020,浏览量:896,Q&A: 0
Protein-protein interactions constitute the molecular foundations of virtually all biological processes. Co-immunoprecipitation (CoIP) experiments are probably the most widely used method to probe both heterotypic and homotypic protein-protein interactions. Recent advances in super-resolution microscopy have revealed that several nuclear proteins ...
