FIG. 5.
PD-L1/L2−/− mice have normal outer retina function. A. Representative raw electroretinogram traces for WT and PD-L1/L2−/− mice. Maximum b-wave amplitude in PD-L1/L2−/− (n = 3, open triangles) and WT (n = 5, open circles) mice, over a range of stimulus intensities, for both scotopic (B) and photopic (C) conditions. Amplitudes are presented as mean ± standard error of the mean. Scotopic response characteristics for WT: Vmax = 883.6 ± 60.1 μV, k = 0.055 ± 0.003 c-s/m2; and for PD-L1/L2−/−: Vmax = 832.5 ± 122.1 μV, k = 0.066 ± 0.004 c-s/m2.
