Using Microtiter Dish Radiolabeling for Multiple In Vivo Measurements Of Escherichia coli (p)ppGpp Followed by Thin Layer Chromatography Llorenç Fernández-Coll1, Michael Cashel1 1Intramural Research Program, Eunice Kennedy Shriver NICHD, NIH The growth of radiolabeled bacterial cultures in microtiter dishes facilitates high throughput sampling that allows multiple technical and biological replicate assays of nucleotide pool abundance, including that of (p)ppGpp. The effects of growth transitions provoked by sources of physiological stress as well as recovery from stress can be monitored.
Analysis of Zebrafish Larvae Skeletal Muscle Integrity with Evans Blue Dye Sarah J. Smith*1,2, Eric J. Horstick*3,4, Ann E. Davidson1,2, James Dowling1,2,4 1Program in Genetics & Genome Biology, The Hospital for Sick Children, 2Department of Molecular Genetics, The University of Toronto, 3Program in Genomics of Differentiation, Eunice Kennedy Shriver National Institute of Child Health and Human Development, 4Departments of Pediatrics and Neurology, University of Michigan In this study, we describe a straightforward method to perform Evans Blue Dye (EBD) analysis on zebrafish larvae. This technique is a powerful tool for the characterization of skeletal muscle integrity and delineation of zebrafish models of muscular dystrophy, and is a valuable method for the development of novel therapeutics.
