Beach1, Todd D. Gruber1 1Department of Molecular Biology and Chemistry, Christopher Newport University Here, we present a protocol to use thiazole orange for the detection of DNA in gel electrophoresis experiments. The use of thiazole orange allows elimination of ethidium bromide, and fluorescence detection can be achieved with either UV or blue light. Behavior Place and Response Learning in the Open-field Tower Maze Olga Lipatova1, Matthew M. Campolattaro1, Donna J. Toufexis2, Erin A. Mabry1 1Department of Psychology, Christopher Newport University, 2Department of Psychological Science, University of Vermont The Open-field Tower Maze (OFTM) is a maze created to study the behavioral and neural mechanisms of spatial learning (e.g., place- or response-learning) in rats. This maze is especially useful for experimenters who want to use a non-stressful maze paradigm to investigate spatial learning in their research.
