Processing of [¹²⁵I]LL1 bound to T-cell lymphoma HUT 78. After antibody binding, the cells were washed and the fate of the bound antibody was followed for up to 21 hr: (•), cell-bound; (▪), intact in supernatant (TCA precipitable); (▴), degraded in supernatant. Values shown are means±standard deviations of duplicates; any standard deviations not seen (which are almost all) are too small to be visible above the symbols. Results shown are representative of two experiments. The total c.p.m. binding was 127 755 c.p.m., of which 99·3% was specifically inhibitable by excess cold LL1.
