    Freeze-fracture-etching Electron Microscopy for Facile Analysis of Yeast Ultrastructure
    Authors:  Takuma Tsuji and Toyoshi Fujimoto, date: 09/20/2017, view: 4955, Q&A: 0
    [Abstract] We describe a streamlined method that enables the quick observation of yeast ultrastructure by electron microscopy (EM). Yeast cells are high-pressure frozen, freeze-fractured to cut across the cytoplasm, and freeze-etched to sublimate ice in the cytosol and the organelle lumen. The cellular structures delineated by these procedures are coated by ...
    Metabolite and Fatty Acid Analysis of Yeast Cells and Culture Supernatants
    Authors:  Liwei Chen and Wei Ning Chen, date: 09/05/2014, view: 10950, Q&A: 0
    [Abstract] Metabolite and fatty acid analysis play important roles in evaluating the metabolic state of microorganisms. To examine the growth state and metabolism response of cells to environmental stress or genetic modification, intracellular and extracellular metabolites including fatty acids are usually analyzed to help understand the cellular biochemical ...
    Metabolic Labeling of Yeast Sphingolipids with Radioactive D-erythro-[4,5-3H]dihydrosphingosine
    Authors:  Takefumi Karashima, Kentaro Kajiwara and Kouichi Funato, date: 08/20/2013, view: 6420, Q&A: 0
    [Abstract] Yeast sphingolipids can be metabolically labeled with exogenously added radioactive precursors. Here we describe a method to label ceramides and complex sphingolipids of Saccharomyces cerevisiae with a radioactive ceramide precursor, D-erythro-[4, 5-3H]dihydrosphingosine. This protocol is used to study the biosynthesis, ...
