Cross reactive binding and epitope mapping of anti-V3 mAbs by ELISA All the plasma samples from patients recruited for this study, were previously screened for their relative binding to V3C and V3B peptides (Andrabi et al., submitted) and the data is here shown for only three samples from which anti-V3 mAbs were isolated ( Figure 1C ). The peptide binding assays revealed the cross reactive binding potential of the anti-V3 Abs in the plasma sample 277 and 904 while 903 showed subtype-C V3 specific binding.
