FIG. 2.
Dendrogram of the 21 anti-V3 MAbs showing the immunologic relationships defined by their reactivities with 50 V3 peptides. The dark horizontal line denotes the point in the tree at which Hartigan’s algorithm delineates the most appropriate number of clusters—five in this case. Each cluster is numbered at the bottom of the figure. The vertical axis shows the distance between merged clusters measured in mean-squared LSR units.
