The cross neutralizing activities of plasma antibodies from 80 HIV-1 infected drug naïve individuals from north India against the tier 2 subtype-B and C viruses indicated on the top of the table. Each virus is designated with its subtype (subtype-C and subtype-B; superscript alphabet on left). The AIIMS ID of the patient samples is given on the left of the table followed by the subtype of viruses they were infected with (C- subtype-C, A- subtype-A and ND- not determined). The numerical values in boxes are the 50% neutralization titers (ID50) defined as the dilution of plasma which neutralized 50% of viral infection in the assay. For clarity, this information is coded: ID50>1000 (Bold), ID50 = 61–1000 (Italic) and <60, where ID50 was not reached. Each experiment was performed at least two independent times.
