embryo (WME) is demonstrated with single-photon excitation (1PE) confocal fluorescence
microscopy and fluorescence in situ hybridization. Expression domains of Pax-6 mRNA
transcripts were labeled with an in situ hybridization probe that is a RNA sequence
complementary to the cloned gene fragment and were rendered visible using two
fluorochrome-conjugated antibodies that fluoresce at peak wavelengths of λF= 0.525 μm …
