Expression of Rax transcription factors in Xenopus laevis. (A) RT-PCR was performed using total RNA (1 μg) from embryo heads (stages 35/36 and 39/40) or adult retinas and primers to amplify histone H4 and the three Rx paralogs (xRax1b, 2a and 2b). (B) Quantitative analysis of Rax expression levels in adult retinas by qRT-PCR.
