FIG 2.

Reactivity of sera from llamas immunized with gD. A 1:100 dilution of sera collected before the initiation of immunization (naive) and after the second through fourth immunizations (Im. #2 to #4) was serially diluted 10-fold and tested in an ELISA for reactivity to gD2. The llama sera from Immunizations 2 to 4 demonstrate higher reactivity to gD2 than naive sera, demonstrating that the llama mounted an antibody response against the gD2 immunizations. Data represent the averages from three wells, and error bars are standard deviations.
