    Immunophenotyping and Intracellular Staining of Fixed Whole Blood for Mass Cytometry (CyTOF)
    Authors:  Sangeeta Kowli and Holden Maecker, date: 09/05/2020, view: 1254, Q&A: 0
    In this report, we present the implementation of mass cytometry for intracellular staining using fixed whole blood. In our assay described here, 250 µl of whole blood, is stimulated in vitro with PMA/ionomycin (or left unstimulated), in the ...
    Preparing Immunolocalization Slides of Maize Meiotic Chromosomes for Three-dimensional Microscopy
    Authors:  Qian Du and Wojciech P. Pawlowski, date: 07/20/2020, view: 461, Q&A: 0
    The protocol provides fully detailed steps for preparing microscopic slides of acrylamide-embedded maize meiotic cells. This method is particularly useful for examining chromatin structure and chromosome arrangement without destroying the ...
    Chiasma Counting in Maize Male Meiocytes
    Authors:  Gaganpreet K. Sidhu and Wojciech P. Pawlowski, date: 05/05/2020, view: 963, Q&A: 0
    This protocol combines a classical chromosome spreading technique with 3-dimensional image reconstruction for visualization of bivalent configurations during meiosis to aid chiasma counting.
    Immunolabeling of Maize Meiocytes
    Authors:  Mateusz Zelkowski and Wojciech P. Pawlowski, date: 04/05/2020, view: 1087, Q&A: 0
    This protocol describes a quick method for immunolocalization of meiotic proteins in maize. It includes a fixation step that allows for long-term storage of material and provides good preservation of chromatin structure.
    Double Labeling of Microtubules and Actin Filaments in Maize Leaf Division Zone
    Authors:  Qiong Nan, Janette Mendoza and Michelle Renee Facette, date: 06/20/2019, view: 2054, Q&A: 1
    Maize leaves grow in a gradient. The base of young maize leaves contains a high proportion of symmetrically and asymmetrically dividing cells, making the leaf an effective model system for the study of cell division. Here, we describe a double ...
    Staining Maize Epidermal Leaf Peels with Toluidine Blue O
    Authors:  Marschal A. Bellinger, Sukhmani K. Sidhu and Carolyn G. Rasmussen, date: 04/20/2019, view: 4339, Q&A: 0
    Maize is an important model organism for understanding cell patterning and development. The regular patterning of maize leaf epidermal cells has previously been characterized using the dye toluidine blue O (TBO). The polychromatic dye TBO ...
    Glue Impressions of Maize Leaves and Their Use in Classifying Mutants
    Authors:  Lindy A. Allsman, Raquel N. Dieffenbacher and Carolyn G. Rasmussen, date: 04/05/2019, view: 2412, Q&A: 0
    Maize cells are surrounded by cell walls that can be easily visualized using a simple protocol outlined below. A glue impression is an imprint of maize epidermal cells on a glass slide made using a cyanoacrylate-based glue (super glue) that produces ...
    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: 2235, 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: 4135, 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; ...
    Combinations of Patch-Clamp and Confocal Calcium Imaging in Acutely Isolated Adult Mouse Amygdala Brain Slices
    Authors:  Erin E. Koffman and Jianyang Du, date: 08/05/2018, view: 4323, 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 ...
