Sonication-facilitated Immunofluorescence Staining of Late-stage Embryonic and Larval Drosophila Tissues In Situ
Published on: August 14, 2014
Abstract:
INTRODUCTIONDrosophila embryos can be stained with specific fluorescent probes or antibodies through either direct or indirect immunofluorescence. In particular, several effective probes exist for visualizing DNA. 4',6-diamidino-2-phenylindole (DAPI) is a commonly used DNA-binding dye. Because it is specific for double-stranded DNA, no prior RNase treatment is required. While the embryo staining method described here uses DAPI, other fluorescent DNA probes can be processed similarly.
