Regional Centre for Biotechnology 3 articles published in JoVE Behavior Tracking Sugar-Elicited Local Searching Behavior in Drosophila Manal Shakeel1,2, Shivam Kaushik3, Teiichi Tanimura4, Axel Brockmann1, Pinky Kain3,5 1National Centre for Biological Sciences, 2The University of Trans-Disciplinary Health Sciences and Technology, 3Regional Centre for Biotechnology, 4Neural Circuit Group, Division of Biological Science, Graduate School of Science, Nagoya University, 5Perelman School of Medicine, University of Pennsylvania This protocol describes a behavioral assay for recording sugar-elicited search behavior using Drosophila melanogaster. The assay can be utilized to study feeding and foraging-related behaviors, as well as the underlying neuronal mechanisms. Cancer Research Zebrafish Larvae as a Model to Evaluate Potential Radiosensitizers or Protectors Amlan P. Mohapatra*1,3, Deepti Parida*1,3, Debasish Mohapatra1,4, Usharani Nayak2,3, Rajeeb K. Swain2, Shantibhusan Senapati1 1Tumor microenvironment and animal models lab, Institute of Life Sciences, 2Vascular Biology lab, Institute of Life Sciences, 3Regional Centre for Biotechnology, 4School of Biotechnology, KIIT University The zebrafish has recently been exploited as a model to validate potential radiation modifiers. The present protocol describes the detailed steps to use zebrafish embryos for radiation-based screening experiments and some observational approaches to evaluate the effect of different treatments and radiation. Biochemistry In Vitro Characterization of Histone Chaperones using Analytical, Pull-Down and Chaperoning Assays Ruchir C.
