Quantitation of A2E and iso-A2E in eye cups of Abcr–/– mice expressing either the Leu-450 or Met-450 variant of Rpe65. Levels were determined as integrated peak areas normalized to an external standard of A2E. (A) A2E and iso-A2E in eyes of Abcr–/– mice (age 8.5–9 months). Values (mean ± SD) are expressed as picomoles per eye and are based on two to five samples and two eye cups per sample. (B) Eye cups obtained from Abcr–/– mice (age 15 months). Values are based on single samples with two eyes per sample.
