Kögler1, Patrick Müller1,2 1Systems Biology of Development Group, Friedrich Miescher Laboratory of the Max Planck Society, 2University of Konstanz Embryological manipulations such as extirpation and transplantation of cells are important tools to study early development. This protocol describes a simple and effective transplantation device to perform these manipulations in zebrafish embryos. Biology A Cell Free Assay to Study Chromatin Decondensation at the End of Mitosis Anna K. Schellhaus*1, Adriana Magalska*2, Allana Schooley1, Wolfram Antonin1 1Friedrich Miescher Laboratory, Max Planck Society, 2Nencki Institute of Experimental Biology, Polish Academy of Sciences The molecular mechanisms of the decondensation of highly compacted mitotic chromatin are ill-defined. We present a cell-free assay based on mitotic chromatin clusters isolated from HeLa cells and Xenopus laevis egg extract that faithfully reconstitutes the decondensation process in vitro. Developmental Biology Measuring Protein Stability in Living Zebrafish Embryos Using Fluorescence Decay After Photoconversion (FDAP) Katherine W. Rogers1, Alexander Bläßle2, Alexander F. Schier1, Patrick Müller2 1Department of Molecular and Cellular Biology, Harvard University, 2Systems Biology of Development Group, Friedrich Miescher Laboratory of the Max Planck Society Protein levels in cells and tissues are often tightly regulated by the balance of protein production and clearance. Using Fluorescence Decay After Photoconversion (FDAP), the clearance kinetics of proteins can be experimentally measured in vivo.
