Dark-adapted RBC responses of <i>WT</i> and <i>Pd^−/−</i> mice.

<p>(A) Representative families of responses to flashes that activated between 0.1 and 60 R*/rod. (B) Population average Intensity-Response (I-R) relationships from the averaged response amplitudes of 14 <i>WT</i> (black) and 11 <i>Pd^−/−</i> (gray) dark-adapted RBCs. Error bars represent SEM. Curves were fitted using the Hill equation with Hill coefficients of 1.31 and 1.70 for <i>WT</i> and <i>Pd^−/−</i>, respectively.
