The cross neutralizing activities of plasma antibodies from HIV-1 infected drug naïve sample #254 against a panel of subtype-A, B, C tier 1 and 2 viruses indicated on left. The numerical values on the extreme right of table represent the mean 50% neutralization titers (ID50) defined as the reciprocal dilution of plasma which neutralized 50% of viral infection in the assay. For clarity, this information is coded; ID50> 1000 (Bold), ID50= 100-l000 (Bold Italic), ID50= 61–100 (Italic) and ID50<60, where 50% neutralization was not reached. Each experiment was performed at least two independent times and in duplicates.
