Figure 1From: Isolation of a human-like antibody fragment (scFv) that neutralizes ricin biological activityRicin neutralization in cell-based assays. Ricin neutralization capacity of scFv 43RCA, calculated as (signal in average test wells minus signal in 4 no-toxin control wells)/(signal in 4 toxin-only control wells minus signal in 4 no-toxin control wells) and expressed as a function of 43RCA concentration ("ng/ml"). 43RCA IC50 = 23 ± 3 ng/mlBack to article page
