Figure 3. Heat treatment of H1N1pdm09 reference antigen to evaluate antibody specificity by SRID using NIBSC (anti-H1N1pdm09) reference antiserum and rHA1-H1N1pdm09 sheep antiserum.

Figure 3

Dilutions of H1N1pdm09 (A/California/7/2009) reference antigen were analyzed by SRID assay before or after heat treatment at 56°C for 3 hours, using either the homologous NIBSC reference antiserum (A) or the alternative CBER rHA1-sheep antiserum (B).
