FIG. 1 A schematic diagram of the principle and manipulation of the double-sandwich ELISA for pandemic (H1N1) 2009 virus (pH1N1 ELISA). HA, haemagglutinin; HRP, horseradish peroxidase; mAb, monoclonal antibody; tetramethylbenzidine (TMB).

FIG. 2 Correlation between the signal/cut-off (S/CO) value of pandemic (H1N1) 2009 ELISA and cycle threshold (CT) value of the CDC real-time RT-PCR in 91 pandemic H1N1 patients. Broken lines indicate the lower detection of the Pan-H1 ELISA.
