According to authors cFgfr3 and quail Fgfr4 were a gift from Dr C. Marcelle; Marics et al., 2002. As information provided was insufficient to verify exact sequence used to synthesize probe, the sequence below was obtained from NCBI (acc #NM_205509). This sequence shows strong similarity to Stathmin-like 3, NW_001471567 on Chromosome 20 for nt 3241-3693. Nucleotides 1-3230 match with Fgfr3. These were selected to represent the probe.
