Binding of LL2-onconase conjugate to Daudi cells.
Competitive binding analysis of LL2 or LL2-onconase inhibition of binding of [125I]-labeled LL2 IgG2a antibody to human Daudi lymphoma cells expressing the CD22 antigen. Binding analyses were conducted as described in “Materials and methods.” Duplicates from at least 2 experiments were pooled and plotted ± SEM. LL2, solid circles; LL2-onconase (LL2-Onc), open circles.
