Figure 3.
Binding of parent <CD138> and -B2G variants to the hCD138 antigen. Surface Plasmon Resonance with monomeric CD138 protein as analyte assesses (A) monovalent and (B) bivalent binding. SPR profiles of Hg-Lw and Hg-Lg variants show a weak remaining resonance when analyzed in the bivalent assay.
