Analysis of relative GFP expression of RS1 promoter constructs

Promoter construct	Number of tadpoles (i.e. surviving G418 selection)	Percentage with detectable GFP at dpf14a (%)	Number examined by confocal microscopy
XOP	13	92	3
WT	11	73	4
mCRE1	23	9	4
mCRE2	18	67	6
mCRE13	19	5	5
mNRE	15	53	6
mNR2E3	22	59	4

^aAs determined by fluorescent screening of tadpoles eyes in vivo.
