Amounts of 11-cis-retinal at PND14 in Rho^+/+, Rho^+/− and Rho^P23H/+ mice^a

Mice	11-cis-retinal (pmol/eye)	n (total eyes)
Rho+/+	171 ± 25.1	4 (14)
Rho+/−	89.5 ± 13.9	5 (26)
RhoP23H/+	89.8 ± 7.6	3 (16)

^aAmounts of 11-cis-retinal in dark adapted eyes were analyzed by normal phase high-performance liquid chromatography (HPLC). There was no significant difference in 11-cis-retinal content between Rho^+/− and Rho^P23H/+ mice at PND14. Consistent with the single Rho^+/+ allele, the amount of 11-cis-retinal in Rho^+/− and Rho^P23H/+ mice was about half of that in Rho^+/+ mice. Values are means ± SD. n, number of repeated analyses.
