    Visualization and Quantitation of Wg trafficking in the Drosophila Wing Imaginal Epithelium

    Secretory Wnt trafficking can be studied in the polarized epithelial monolayer of Drosophila wing imaginal discs (WID). In this tissue, Wg (Drosophila Wnt-I) is presented on the apical surface of its source cells before being internalized into the

    Imaging and Fluorescence Quantification in Caenorhabditis elegans with Flow Vermimetry and Automated Microscopy
    Authors:  Elissa Tjahjono, Alexey V. Revtovich and Natalia V. Kirienko, date: 05/20/2021, view: 674, Q&A: 0

    Gene activation and cellular biomarkers are commonly monitored using fluorescent signals from transgenic reporters or dyes. These quantifiable markers are critical for biological research and serve as an incredibly powerful tool, even more so when

    Analysis of TORC1-body Formation in Budding Yeast
    Authors:  Ryan L. Wallace, Eric Lu, Arron Sullivan, James E. Hughes Hallett and Andrew P. Capaldi, date: 04/05/2021, view: 558, Q&A: 0

    The Target of Rapamycin kinase Complex I (TORC1) is the master regulator of cell growth and metabolism in eukaryotes. In the presence of pro-growth hormones and abundant nutrients, TORC1 is active and drives protein, lipid, and nucleotide synthesis

    Ligand and Carbohydrate Engagement (LACE) Assay and Fluorescence Quantification on Murine Neural Tissue
    Authors:  James M. Clegg and Thomas Pratt, date: 03/20/2021, view: 664, Q&A: 0

    The interaction between cell surface heparan sulphate and diffusible ligands such as FGFs is of vital importance for downstream signaling, however, there are few techniques that can be used to investigate this binding event. The ligand and

    Molecular and Phenotypic Characterization Following RNAi Mediated Knockdown in Drosophila
    Authors:  Saurabh Jayesh Kumar Mehta, Pradyumna A. Joshi and Ram Kumar Mishra, date: 02/20/2021, view: 1119, Q&A: 0

    Loss of function studies shed significant light on the involvement of a gene or gene product in different cellular processes. Short hairpin RNA (shRNA) mediated RNA interference (RNAi) is a classical yet straightforward technique frequently used to

    DigiTAG–a RNA Sequencing Approach to Analyze Transcriptomes of Rare Cell Populations in Drosophila melanogaster
    Authors:  Lisa Landskron, Francois Bonnay, Thomas R. Burkard and Jürgen A. Knoblich, date: 11/05/2020, view: 1308, Q&A: 0

    Cell-type specific transcriptional programs underlie the development and maintenance of organs. Not only distinct cell types within a tissue, even cells with supposedly identical cell fates show a high degree of transcriptional heterogeneity.

    Production and Bioassay of a Diffusible Factor that Induces Gametophyte-to-Sporophyte Developmental Reprogramming in the Brown Alga Ectocarpus
    The brown alga Ectocarpus has a haploid-diploid life cycle that involves alternation between two multicellular generations, the sporophyte and the gametophyte. Life cycle generation is not determined by ploidy but by a genetic system that ...
    In vitro Induction and Detection of Acrosomal Exocytosis in Human Spermatozoa
    Authors:  Shenae L. Cafe, Amanda L. Anderson and Brett Nixon, date: 07/20/2020, view: 1418, Q&A: 0
    The acrosome reaction is a highly regulated exocytotic event that primes spermatozoa for successful fertilization. Upon induction, acrosomal exocytosis proceeds via a wave of vesiculation that radiates across the sperm head, destabilizing the ...
    Organotypic Slice Culture of the Embryonic Mouse Brain
    Authors:  James M. Clegg and Thomas Pratt, date: 07/05/2020, view: 1401, Q&A: 0
    Organotypic slice culture is a powerful technique for exploring the embryonic development of the mammalian brain. In this protocol we describe a basic slice culture technique we have used for two sets of experiments: axon guidance transplant assays ...
    Ex vivo Culture Assay Using Human Hair Follicles to Study Circadian Characteristics
    Authors:  Atsuhiro Nishida, Yoshiki Miyawaki, Koichi Node and Makoto Akashi, date: 06/05/2020, view: 1440, Q&A: 0
    Ex vivo culture assays of biopsy specimens are advantageous for the experimental evaluation of human circadian characteristics. We developed a simple and non-invasive experimental evaluation method for monitoring the expression of circadian ...
