Fig 4.

Reactivity profiles of anti-SalI and anti-DEKnull sera with recombinant antigens. Each antiserum was tested by endpoint dilution for cross-reactivity with homologous and heterologous refolded antigens. Antigen preparations were adsorbed onto wells of a micro titer plate and allowed to react with different dilutions of the antisera. Solid and broken lines represent recombinant SalI and recombinant DEKnull, respectively. Each point on the curves represents the mean of triplicate wells, while error bars represent ±standard deviation.
