Table 2.

Effect of anti-6.4 S hyalin serum on L.pictus exogastrulation, archenteron elongation and attachment. These data are from five separate experiments and the numbers presented in the table are the means (+/− the standard error of the mean) for each condition. A total of 14,000 embryos was used in a total of five separate experiments.
