  1. aHemolytic activity assays carried out using the tube assay method as described in the Methods. Hemolysis by M93Sm was given the value of 1.00. The data are representative of two independent experiments, each with three replicates, ± one standard deviation (SD).
  2. bStatistically different from hemolytic activity for M93Sm (P < 0.05).
