NEUROBIOLOGY. For the article “Phototransduction in transgenic mice after targeted deletion of the rod transducin α-subunit” by P. D. Calvert, N. V. Krasnoperova, A. L. Lyubarsky, T. Isayama, M. Nicoló, B. Kosaras, G. Wong, K. S. Gannon, R. F. Margolskee, R. L. Sidman, E. N. Pugh, Jr., C. L. Makino, and J. Lem, which appeared in number 25, December 5, 2000, of Proc. Natl. Acad. Sci. USA (97, 13913–13918; First Published November 28, 2000; 10.1073/pnas.250478897), the authors note that the exponents of some entries in Table 1 were misprinted. The correct values appear below.
Table 1.
ERG parameters
| Type | bmax, μV | Sensitivity: 357 nm (photons−1·μm2) | Sensitivity: 513 nm (photons−1·μm2) | Sensitivity ratio 357/513 |
|---|---|---|---|---|
| WT background | 98 ± 16, 6 | (1.7 ± 0.5) × 10−4, 6 | (3.0 ± 0.9) × 10−5, 6 | 5.2 ± 0.5, 6 |
| Trα−/− | 120 ± 11, 9 | (1.9 ± 0.5) × 10−4, 5 | (6.8 ± 1.2) × 10−5, 5 | 3.0 ± 0.8, 5 |
| Trα−/− background | 119 ± 13, 5 | (1.1 ± 0.1) × 10−4, 5 | (3.4 ± 0.4) × 10−5, 5 | 3.5 ± 0.4, 5 |
Values are means ± SEM, n. bmax is the maximal amplitude of the b-wave. Sensitivity is the fraction of the maximal b-wave response divided by the photon density at the cornea for responses in the linear range, i.e., <0.3 bmax (18). Background signifies continuous exposure to 540-nm light during the measurements.
