Sample Preparation and Imaging of Exosomes by Transmission Electron Microscopy Min Kyo Jung1, Ji Young Mun2 1Department of Convergence Medicine, University of Ulsan College of Medicine and Asan Institute for Life Sciences, Asan Medical Center, 2Synaptic Circuit Plasticity Laboratory, Department of Structure and Function of Neural Network, Korea Brain Research Institute This protocol describes the various techniques necessary for transmission electron microscopy including negative staining, ultrathin sectioning for detailed structure, and immuno-gold labelling to determine the positions of specific proteins in exosomes.
RNA Interference-based Investigation of the Function of Heat Shock Protein 27 during Corneal Epithelial Wound Healing Aeri Yoo*1, Hyun-Min Park*2, Soon-Suk Kang2, Eun-Soon Kim2, Hungwon Tchah2, Jae Yong Kim2 1Department of Ophthalmology, Saevit Eye Hospital, 2Department of Ophthalmology, University of Ulsan College of Medicine, Asan Medical Center Herein, we present a protocol to use heat shock protein 27 (HSP27)-specific small interfering RNA to assess the function of HSP27 during corneal epithelial wound healing. RNA interference is the best method for effectively knocking-down gene expression to investigate protein function in various cell types.
