Recognition of huIL-15 (a) and siIL-15 (b) by sera from immunized monkeys. The ELISA plate was coated with 1 µg/ml of commercial huIL-15 or siIL-15, and it was incubated with the pool of sera from each group (200 µg mhIL-15, 200 µg IL-15 D8SQ108S, 350 µg IL-15 D8SQ108S and vehicle control) diluted 1:4000. All sera tested were collected before beginning the scheme (pre-immune) and 15 days after the second and third immunizations. Columns represent the mean values of OD450nm ± standard deviation (SD) from two independent experiments performed in triplicate
