Figure 2From: Uptake of 3H-cAMP by retinal pigment epithelium isolated from bluegill sunfish (Lepomis macrochirus)Dose response analysis of cyclic AMP's effects on pigment granule aggregation in isolated RPE cells. The t0 PI was 0.95 ± 0.02 (n = 7) after a 30 minute preculture. RPE cells were cultured in cAMP for 30 minutes. The control PI was 0.91 ± 0.02 n = 7, except where noted.Back to article page
