Two-colour fluorescent in situ hybridization of CjapCSP1 and CjapCSP12 transcripts in Camponotus japonicus worker antennae.
Single optical plane of antennal surfaces visualised by fluorescent dies with CjapCSP1 (green) and CjapCSP12 (red) anti-sense probes (A,B) or sense probes (C). (A) Cells labelled with both CjapCSP1 and CjapCSP12 probes. Yellow colour indicates co-labelling with two probes. (B) Cells mainly labelled with CjapCSP12 anti-sense probes. (a,b) Higher magnification of the areas boxed in (A,B), respectively. Scale bars indicate 20 μm.
