Probe:	P450RAI cDNA
Probe preparation:	labelled with digoxigenin
Visualized with:	Alkaline phosphatase

Structure	Level	Pattern	Image	Note
TS21: retina	Present	Regionally restricted	4B left	Expression was detected in a narrow stripe running horizontally across the full width of the retina.

Structure	Level	Pattern	Image	Note
TS27: retina	Present	Regionally restricted	4B right	Expression was detected in a narrow horizontal stripe in the periphery of the retina. It was not detectable in the central region.

Structure	Level	Pattern	Image	Note
TS19: retina	Present	Regionally restricted	5E	Expression was detected in a stripe in the retina. Expression seems to straddle the ventral border of immunostaining for Aldh1a1 (Ahd2). Single labeled cells barely reach the vitreal margin.

Structure	Level	Pattern	Image	Note
TS21: retina	Present	Regionally restricted	5G	Expression was detected in a stripe slightly dorsal to the optic disc and ventral to immunostaining for Aldh1a1 (Adh2). Selected cell labeling was restricted to the outer retina containing proliferating cells but absent from the inner region.

Structure	Level	Pattern	Image	Note
TS13: eye	Present	Regionally restricted	6_Top left: E8.5	Expression was detected in the dorsal part of the early eye vesicle.

Structure	Level	Pattern	Image	Note
TS14: optic vesicle	Strong	Regionally restricted	6_Top right: E9	Strong expression was detected in the dorsal part of the eye vesicle.

Structure	Level	Pattern	Image	Note
TS14: optic vesicle	Present	Regionally restricted	6_Bottom: Cyp26	Expression was detected in the dorsal part of the eye vesicle. Expression overlaps with Aldh1a1 (Ahd2).
TS14: optic vesicle neural ectoderm	Present	Regionally restricted	6_Bottom: Cyp26	Expression was concentrated at the ventricular side of the neural epithelial cells.
