A Blood-retina Barrier Permeability Assay in Young Mice Using Sulfo-NHS-LC-biotin Perfusion
    Authors:  Entzu Wan, Mitsutaka Ogawa and Tetsuya Okajima, date: 10/20/2018, view: 76, Q&A: 0
    Brain and retinal vasculatures exhibit restricted vascular permeability known as blood-brain barrier and blood-retina barrier. Vascular permeability can be evaluated by perfusion of the amine reactive ester derivatives of biotin such as ...
    Dissection and Whole Mount Staining of Retina from Neonatal Mice
    Authors:  Mitsutaka Ogawa and Tetsuya Okajima, date: 10/05/2018, view: 151, Q&A: 0
    Here we provide a detailed protocol for whole mount staining of mouse retina. This protocol was used to analyze retinal angiogenesis in newborn mice (Sawaguchi et al., 2017) by modifying the original protocols (Powner et al., 2012; ...
    Striatal Synaptosomes Preparation from Mouse Brain
    Authors:  Shiqi Ma and Alexander Sorkin, date: 09/05/2018, view: 234, Q&A: 0
    The striatum is located in the subcortical region of the forebrain, it contains medium spiny neurons, cholinergic interneurons and GABAergic interneurons, and receives dopaminergic projection in the nigrostriatal pathway. This protocol provides a ...
    Isolation of Murine Brain and Lung Microvascular Endothelial Cells
    Authors:  Ailing Zhang, Shogo Sawaguchi, Entzu Wan, Mitsutaka Ogawa and Tetsuya Okajima, date: 08/20/2018, view: 452, Q&A: 0
    This protocol describes how to isolate murine endothelial cells from newborn mice brain and 3-month-old mice lung by modifying the original protocols (Sobczak et al., 2010; Ruck et al., 2014). We have used the protocol to analyze ...
    Combinations of Patch-Clamp and Confocal Calcium Imaging in Acutely Isolated Adult Mouse Amygdala Brain Slices
    Authors:  Jianyang Du and Erin Elizabeth Koffman, date: 08/05/2018, view: 460, Q&A: 0
    Calcium imaging is a powerful technique in the study of neuronal physiology, as it avoids the enzyme treatment on neurons and is able to study the neuronal activities in vivo. Using calcium-imaging techniques, we are able to monitor the ...
    Protocol for the Isolation and Super-resolution dSTORM Imaging of RyR2 in Cardiac Myocytes
    Authors:  Yufeng Hou, Christopher Le, Christian Soeller and William E. Louch, date: 08/05/2018, view: 527, Q&A: 0
    Since its inception, super-resolution microscopy has played an increasingly important role in the discovery and characterization of nanoscale biological structure. dSTORM, which is one of the most commonly applied methods, relies on stochastic ...
    High-throughput YO-PRO-1 Uptake Assay for P2X7 Receptors Expressed in HEK Cells
    Authors:  Akira Karasawa and Toshimitsu Kawate, date: 07/20/2018, view: 647, Q&A: 0
    P2X7 receptors are extracellular ATP-gated ion channels that play broad physiological and pathological roles in animals (Sluyter, 2017). Activation of P2X7 receptors lead to the opening of membrane channels permeable for small cations like Na+ ...
    Quantifying Gene Expression Directly from FACS Using Hydrolysis (TaqMan) Probes on Flash-frozen Cells
    Authors:  Kirsten A. Copren, Oyang Teng, Cassandra J. Adams, Cláudia Bispo and Michael Lee, date: 04/20/2018, view: 1173, Q&A: 0
    The TaqMan Gene Expression Cells-to-CtTM Kit enables reverse transcription directly from cell lysates without the need for isolating RNA. The recommended input range for the lysis reaction is between 10-105 cells, though the ...
    RNA Extraction from Wistar Rat Cochlea for qRT-PCR
    Authors:  Janaína Cândida Rodrigues and Rubens Vuono de Brito Neto, date: 12/05/2017, view: 1820, Q&A: 0
    Otology research has developed considerably in recent years and molecular analysis is crucial to identify metabolic pathways and therapeutic targets. However, the structure of the cochlea limits the amount of cell mass, and special care is required ...
    Cryopreservation of Human Serum
    Authors:  Yael Rosenberg-Hasson and Holden Maecker, date: 11/05/2015, view: 3615, Q&A: 0
    This protocol describes how to collect and aliquot human serum and store at -80 °C for future cytokine/chemokine/protein profile analysis.
    Please use personal protective equipment (PPE) as required when handling samples with potential ...
