Fig. 4. Temporal expression of HrFGFR. Northern blots of poly(A)⁺ RNA prepared from the fertilized eggs (F), 64-cell stage embryos (64), neurulae (N), and tailbud-stage embryos (TB), hybridized with a ³²P-labeled probe prepared from the C-terminal domain (upper) and Ig3 domain (lower). Each lane was loaded with 5 µg poly(A)⁺ RNA. Exposure time was 1.5 days.
