Table 1 Comparison of ookinete yield from two purification methods. For each purification method (Nycodenz cushion v magnet), the initial density of ookinetes is expressed per ml of blood. Final yield is expressed as a percentage ± SEM of the pre-separation density, n = 4 experiments, each using the pooled blood from two infected mice. No significant difference was observed in yield between the two methods (Student T-test, p > 0.05).
