Expression analysis of p130Cas EGFP-Bac in cranial ganglia. (a–r) Immunofluorescence for EGFP (green) and 2H3 neurofilament (red) on transverse sections from p130Cas EGFP-Bac (a,b,d,e,g,h,j,k,m,n,p,q) and WT (c,f,i,l,o,r) embryos, through the nodose (a–c,g–i,m–o) and trigeminal (d–f,j–l,p–r) ganglia. ToproIII (blue) was used to counterstain nuclei. Note that p130Cas-driven EGFP expression is high throughout both ganglia. Scale bar: 75 um for (a–c,g–i) and (m–o); 150 um (d–f,j–l) and (p–r).
