Mandai et al. Vol. 139, No. 2, Oct. 20, 1997. Pages 517–528.In the above-mentioned manuscript, “kilodalton” was mistakenly inserted in place of “K_d” in three instances. On p. 522, first column, line 13, the sentence should read “The K_d value was calculated to be the order of 10⁻⁷ M.” Similar errors appear on p. 525, second column, one line from the bottom, and on p. 526, first column, line 6.
