Figure 4From: Isolation of a human-like antibody fragment (scFv) that neutralizes ricin biological activityGrouping of the 19 non redundant scFvs, in the form of phylogenetic tree. The tree root (extreme left) indicates that the scFvs are grouped in two clusters, A (scFvs 48, 11, 34, 9, 47, 13, 30, 37, 7, 15) on the upper part, and B (scFvs 8, 1, 23, 4, 43, 35, 44, 38, 31) on the lower part of the figure.Back to article page
