Microscopy of RNA Polymerase II clusters in live zebrafish embryos

This data set contains raw image data and derived images illustrating clusters of RNA polymerase II as observed in zebrafish embryos. The clusters are labelled by fluorescently marked antibody fragments (Fab) that detect phosphorylation of the C-terminal roman of RNA polymerase II. Antibody fragments were provided by the laboratory of Hiroshi Kimura.
