Stoichiometry between coatomer and p23wt-d. ¹²⁵I-labeled p23wt-d (■) or p23AS-d (●) were incubated with increasing concentrations of coatomer. After centrifugation, the amounts of peptide in the precipitates were determined by counting the ¹²⁵I radioactivity. The error bars indicate standard errors (n = 4).
