Corrections and Clarifications
The report "Cure of xenografted human carcinomas by BR96-Doxorubicin immunoconjugates" by P. A. Trail et al. (9 July, p. 212), inadvertently omitted a reference to unpublished information about the specifics of the chemical synthesis of BR96-DOX conjugates. This information has now been published [D. Willner et al., Bioconjug. Chem. 4, 521 (1993)].
