Binding of ²¹³Bi-anti-EGFR-MAb to selected tumor cell lines. Binding of ²¹³Bi-anti-EGFR-MAb to the cell lines used in this study, LN18 and EJ28Luc, and to the reference cell line OVCAR-3 (3 × 10⁶ cells each) was assayed in triplicate for 30 min on ice to exclude internalization (see Mat. + Meth.). Displayed are mean ± SD.
