  1. The cross neutralizing activities of mAbs generated from Indian patients along with 447-52D (also an anti-V3 antibody), were evaluated against the tier 1 and 2 subtype_A, B, C viruses indicated on the left. The antibodies are shown with antibody IDs (numerical values in bold) at the top of each column. Human anti-parvovirus B19 mAb 1418 was used as negative control. The numerical values in the boxes below are the 50% neutralization titers (IC50) defined as the concentration (μg/ml) of mAb which neutralized 50% of viral infection in the assay. For clarity, this information is coded: IC50 < 1 μg/ml; (Bold), IC50 > 1 μg/ml; (Italic) and >30, where IC50 was not reached. Each experiment was performed at least two independent times.
