Fig 2. Optimal antigen concentration for the in house ELISA.

Fig 2

Recombinant capsid protein (5 μg) was twofold serially diluted on Maxisorp® microplate. Serum samples, previously determined to be positive (n = 5) or negative (n = 5) were evaluated. The data is represented as the mean ± SEM of the OD of each antigen dilution. The arrow indicates the optimal antigen concentration.
