    Immunohistochemistry Staining for Tumor-associated Macrophage Polarization in Murine Subcutaneous Colon Tumor Allografts
    Authors:  Gage J. Greening, Shelby N. Bess and Timothy J. Muldoon, date: 12/05/2018, view: 263, Q&A: 0
    Tumor-associated macrophages are the most abundant immune cells in the tumor microenvironment and may express both anti-tumor and pro-tumor functions depending on their polarization towards an M1 (classical) or M2 (alternative) phenotype, ...
    Generation of Endothelial Cells from Human Induced Pluripotent Stem Cells
    Authors:  Chun Liu, Linling Cheng, Christopher Li Chen and Nazish Sayed, date: 11/20/2018, view: 232, Q&A: 0
    Endothelial cells (ECs), as important constituent of blood vessel are crucial to maintaining vascular tone, and any dysfunction in ECs could lead to many diseases of the vascular system. Due to limited availability of human samples, most of our ...
    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: 281, 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: 419, 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: 451, 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 ...
    Ty1 Retrotransposition Frequency Assay Using a Chromosomal Ty1his3AI or Ty1kanMXAI Element
    Author:  M. Joan Curcio, date: 09/05/2018, view: 370, Q&A: 0
    Here I describe a simple genetic assay to determine the frequency of retrotransposition of a single chromosomal Ty1 element that is marked with the retrotransposition indicator gene, his3AI or kanMXAI. The assay is used to ...
    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: 710, 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: 831, 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: 839, 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: 986, 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+ ...
